polygonal lasso tool randomly self selects areas. This is really frustrating and I am beginning to wonder whether anyone at Adobe ever looks at the comments their customers write here and on adobe forums. It seems to me that Adobe doesn't give a "you know what" about their customers. They make difficult to get in touch with someone. They want you to pay for any kind of support even though they are the ones selling low quality, faulty products. I know of many people who are no longer buying adobe products and I will be joining them. I have had enough. My goodness, even their website is so convoluted that one gets even more frustrated.

Hi Simone,

I'm sorry you feel that way.  Many employees regularly "patrol" the forums specifically in order to hear what users think and to solve users' problems.

In your case, it sounds like you've switched the Lasso tool to the Magnetic Lasso tool.  The former selects only what you include while the latter tries to help you and also selects what's similar to the current selection, based on contrast.  You can switch between the Lasso, Polygon Lasso, and the Magnetic Lasso tools in the Toolbox or by pressing SHIFT+L (for English -- other languages vary).

I hope that helps,

We've also seen the polygonal lasso close unexpectedly or malfunction due to MacOS issues. Those issues are worked around using the WhiteWindowWorkaround plugin for Photoshop versions prior to CC 2014, and the workaround is already in Photoshop CC 2014.
And we had a few issues with several tools on some versions of Wacom drivers - fortunately Wacom is usually quick to fix those issues in their drivers.

This reply was created from a merged topic originally titled Polygonal lasso tool self selects area.

I have been working with photoshop CS5 for almost 2 years and today the polygonal lasso tool randomly closes an unfinished selection. This is extremely frustrating considering that I have deadlines. BTW, does the solution listed for CS6 also apply for CS5 on PC? Any solutions would be greatly appreciated.

Sorry you're having trouble.

It sounds like you're on Windows. What version of Windows are you running? Is Photoshop up to date?

Are you using a Wacom tablet?

It sounds like this was working prior today. Any clues as to what changed? Did you do any software updates, install any new drivers, or add any new extensions?

Have you tried restarting your system?

You could try restoring your preferences:

If you do restore your prefs, please save a copy of your existing prefs in case they turn out to be the culprit. Having the bad prefs can sometimes help us track down the issue.
