I recently updated to latest version of Linux Mint 8 and after installing Aptana, my favourite IDE, I noticed that my mouse buttons would not work when trying to click buttons. I tried re-installing the software and trying eclipse but it still didn’t work. I turned to my trusted friend Google for the problem and I came across this post Problems with Eclipse buttons in Ubuntu 9.10 ,which is a shell script to solve a gtk bug. I have eclipse installed in my home folder under .eclipse. Here is a little tutorial on how you write that script.
Open gedit or similar text editor and type:
Note: Change YOURNAME to your usename!
Save the file in my .eclipse folder as eclipse.sh
Now navigate into the .eclipse folder, you might need to check show hidden files in the view menu. Right click on eclipse.sh and click on properties. Click on permissions. Click on allow file executing as a program.
Update your menu to point to the newly created file eclipse.sh in your .eclipse directory. Eclipse should now load without the mouse problem.
