PHOTOSHOP - Refine Edge Brush Not Working Properly

Hi,
When I try to extract an object from an image I can do a quick selection no problem.
However, when I try to Define the edge, the tool acts as an eraser. Here are some images to illustrate what I mean:








The first image shows the picture set up, the second the quick selection on a background, and the third image shows the effect of using the refine edge tool.
Image four shows the effect of tring to extract an object without a background.
Also, when using the tool, an area around the tool will change, but goes back to what it was when you have finished that stroke.
I have loaded PS onto my laptop, and it works just fine so I am thinking that there is a problem with the computer/program interface. Can anybody help please?

Hi, I can understand your frustration! I'm still somewhat new to photoshop, but I can promise that it does get easier to use! Thanks for attaching the pictures, they make it easier to diagnose the issue! Anyways, the refine edge tool is used to remove unwanted parts of an image or layer, I assume you know this. From the pictures you attached, I can see that you have four layers making up your PhotoShop project. It is very important in the application to always check which layer you have currently selected(if any are). Make sure to check if the layer you have selected is indeed the one you are trying to edit! If this is not the issue, then try checking in the panel located directly above the workspace. I figure you know how to use this panel considering that you have its size utility selected in the second image. To the left of the size utility for the selected tool, you will see different modes for it. Hover over these for two seconds to see the hover-label for each of these modes. Make sure that you have the mode selected that performs the task you are using the tool for! If none of these suggestions work, come back to this thread and I or other forum members will try to help you correct the application error!

Edit: Here's a tutorial I just researched that maybe semi-related to the use of the refine edge tool, hope it helps! Here:http://www.photoshop.com/tutorials/6134

Thanks for thatPie King.
I'm of a mind to think that it is a compatibility issue, because as I have said, I loaded PS onto my laptop, did exactly the same and did this:


What I can't understand is that even if I were to use the refine edge tool rather clumsily, surely it wouldn't erase the areas I have used it on?

Ah, I see. I seem to have misinterpreted the question! It probably had to do with the tool misrendering the image to detect and compare the selected color(s). Next time you run PhotoShop, I would recommend(since you have a 32-bit PC-I'm guessing 4 GB of RAM) changing the priority of the application with task manager. Simply right-click your tool bar or CTRL-ALT-DELETE to bring up the option, then go to processes of tasks tab and right click photoshop.exe. You'll either see an option for priority or an option for details. Clicking details red outed you to the processes or details tab(processes since you have Windows 7). Here you right click photoshop.exe once more, bringing up the option for priority. This brings up a sub-menu. Select either High or the option above it(varies in name), While running PhotoShop, also check your processes running in the background(processes tab of task manager) to make sure PhotoShop is the biggest focus of the CPU. This should speed up PhotoShop(after restarting the applicaction) and lower the chance of encountering more glitches or misfunctions such as the one you experienced. Also, changing the application's priority will typically bring up a warning about potential cause of system instability. Avoid this risk by stopping less used processes while using PhotoShop.

Hi Pie King,
Thanks for the advice.
I've got a Windows 7 Ultimate in 64 bit. AMD Quad core processor running at 4.2 GHz, 16GB ram and an ASUS R7 265 Series Graphics card.
I think all the drivers are up to date.
I'll give your tweaks a go, but as I say, the successful example I have uploaded was done on a Dell Inspiron 15R laptop with an Intel i5 processor.
So i'm not sure it is a power issue. I do know that some of the PS commands are written with a couple of Intel routines in mind, but I am not sure that this is the issue.
I still come back to the issue that even if there were to be a power mis-match, what would cause the refine tool to erase the parts it had been used on?
I had wondered if it is a case that my bios could do with being updated, but I'm not sute that CS6 was written with only the latest bios in mind.

Alright, I wish I could help you further, but if the issue goes beyond the scopes of processing, bugs, or other minor computing errors typically caused by the overclocking of the CPU, I can only suggest reporting the misfunction to the Adobe official forums or the Adobe employees themselves. I hope you find a plausible cause for this error, and I'll be very interested to find out what the source of this issue is!
