Windows 7 File Browser/Windows Exploxer Crashing

[JAKEISCRAZY]

Sometime, at random, when i go to open a file or save one it just freezes up when i click on another location say "Desktop" or click "save", "ok", "open". It give some areas a white washed look and freezes. I wish i could give you a screen shot but it freezes when i try to save it.
