Bug 838693

Description of problem:
The OS hangs or freezes randomly, but especially when I click inside of pop-up dialog boxes while they are still expanding from the top of the window or while installing an addon for firefox or a package thru the "Add/remove software" application, but never freezes when installing in terminal with yum install. 

Version-Release number of selected component (if applicable):
Fedora 15

How reproducible:
Clicking inside a dialog box while still "expanding", or downloading a package thru a .yum or .rpm or thru fedora's installer GUI application, or installing an addon for firefox.

Steps to Reproduce:
Dialog box freeze bug:
Click inside a dialog box while still expanding from the top of window

Installing package freeze bug:
Do not use terminal to install applications, use fedora's GUI software adder.
Note: it does not happen all the time, just most of the time.
  
Actual results:
Freezing/hanging ALWAYS with dialog box bug
Freezing/hanging most of the time with installing bug

Expected results:
Dialog box:
nothing to happen when clicking inside it while still expanding

Installing packages thru GUI:
The application to install correctly.

Additional info: When I installed fedora 15 from a DVD it froze during "Installing bootloader" on the setting "Shrink current partition" so it completely screwed up my hard drive because I had to hard reset (hold the power button) and I had no more windows, my only choice was to completely reset the hard drive and install fedora. 

I am using a Compaq Prestario 64 bit which had Windows 7 before the partitions corrupted thanks to your installer, there is an AMD Sempron 140 processor and Nvidia Geforce with Cuda, 2gb RAM and 500gb hard drive.
