I've had this problem from day one when using buzzsaw.
Whenever I click on any non-folder node (using the left-mouse button) my buzzsaw client crashes. It's an application error in PROJEC~1.EXE:
The instruction at "0x005024a2" referenced memory at "0x016a0000". The memory could not be "written".
Clicking on projects/folders doesn't cause the problem - it only happens with files. My workaround has been to right click on files and download them, but that's getting tedious.
I use IE 6.0 on a Win 2000 machine. Also, my coworkers don't have this problem. Does buzzsaw require certain IE settings to work correctly?
