IntelliJ IDEA not responding to mouse clicks

Question

I have a problem with IntelliJ IDEA Community Edition 12.1.6.
Everything works fine, as long as I have only one project (one window) opened. When I open second/third etc. project, only the first one responds to mouse clicks.
Every other project reacts to keyboard input (Ctrl+TAB, Alt+arrows etc.), but not to mouse input. I'm able to modify code, use keystrokes, so the application is not frozen.
I tried to reinstall the app, no effect. The last update was a couple of weeks ago and the problem appeared today.
I'm using Ubuntu 10.04.

Has anyone here encountered similar problem?
Oh, and is there some magical place, where log files are stored?

Answer 1

I had similar problems like you describe. It's a compatibility problem between IDEA and systems using Gnome (I don't know about KDE), there's probably nothing you can do at the moment to fix it for good, however minimizing/rezising the IDEA window with that project fixed it for me. Try it out if this workaround also works for you.

Answer 2

Restarting my computer fixed the issue.

Answer 3

I faced the similar problem after a major update. All of the mouse events are not working and the shortcuts are also not responding. Only the Alt+F and arrows key can open main menu, then Enter key can select the sub menu.

I noticed that I had once changed the boot Java runtime of the IDE. Then I reset the JVM to default, the problem solved.

Instructions

1. Press Alt+H to open the Help menu and select the Find Action sub item. Because the mouse is not responding and Ctrl+Shift+A is not working. You may only open the dialog by main menu.

2. Type Choose Boot Java Runtime for the IDE action. Use arrows key to select the item. Use Enter to open the dialog.

3. Use Tab key to focus on the Use Default Runtime, Press Enter to confirm.

4. Wait for WebStorm to restart with the new runtime.

Everything will be fine after restart.
