Hello community.

Yesterday I updated to Photoshop CC (2014) and I have been having constant issues with the left mouse button.

At first I thought it was to do with Acrobat Pro DC, however since un-installing that the same issues have persisted.

I am working on a PC.

When in Photoshop I lose functionality with the left mouse button. It will click on things, but anything involving a long click or a click, hold and drag will work maybe one time in 15? and with lots of lag.

For example:
(these are a few examples, it is not limited to this by any means)

- Text tool, cannot highlight a section of text with a click, hold and drag
- Doing a click and hold on a tool icon to have mini menu of other tools will not appear
- Cannot click on a layer to move it around canvas. When layer is selected, can still move with keyboard arrow keys.
- Cannot alt-click when using clone stamp
- Cannot drag out a marquee tool area

etc etc

Essentially, as explained earlier, any functionality involving any use of the left mouse button that is not a normal quick click will not work.

I have tried re-installing my mouse drivers etc with no effect

Additionally, it has caused a similar problem with outlook. I cannot click, hold and drag to highlight text... very weird!

Help me, Obi-Wan Kenobi. You're my only hope....

The only thing I can think of is that some other app or utility is intercepting the events before they get to Photoshop.

Then you have some utility, driver, or hardware problem with the mouse.
Check all the drivers and make sure they are up to date.
Check all your utilities and make sure they are not intercepting mouse events.
And try another mouse just to be sure you don't simply have a bad switch in the mouse, or bad cable.

Bought a new mouse. No improvement.

The only consistent is that the issues started when updated Photoshop...

Photoshop CC 2014 hasn't had an update since December.
And the problems still indicate that something other than Photoshop is messing with mouse events before they get to Photoshop.
