Hey, thanks a lot.
With auto-expand I ment when clicking on folder at left panel all
subfolders will open, so it's much easier to navigate between them
quickly if I need copy/move lot's of things to different locations.
Under XP it was possible to change that behaviour with registry setting,
so I simply had two registry files for that case, one for enabling it
and other disabling quickly. But those reg files won't do anything under
Vista.
Anyway ,your solution is good too, thanks for that tip.
