keyboard doesn't work properly in eclipse ide in ubuntu

Question

I don't know why my juno (eclipse 4.2) IDE started behaving very wierd. Pressing delete button in file2 deletes content in file1. I tried to restore all the settings and key bindings but still it behaves the same. Please help me if someone had this issue and resolved it.

Answer 1

Honestly, I have no clue how to fix that, but I would not loose the time with this type of problems and:

• create the new workspace
• install plugins of your preference
• import existing projects/recreate them

I think there are real challenges out there, and your time is worth to use reasonably.

Otherwise you might get stuck in the irritating behavior of the non-usable IDE

For me, the most of the time, when I'm too much in the trouble noone else is facing this method (possibly as the last option) works :)
