Windows 7: Applications hang when opening or saving files

Windows 7 64
Applications hang when opening or saving files

When I try to open or save a file in some applications the dialogue box starts to open and then it and the application freezes. The affected applications all use Explorer type dialogue boxes, those using XP and older style dialogue boxes are OK.

Explorer itself works OK and I can open files by double clicking.

When the problem started there had been no significant changes to the system, no new applications and no updates.

Any thoughts on what the problem may be or how to isolate it?

Problem solved

The problem seems to be with fdWNet.dll .

I applied a hotfix from Microsoft and that seems to have fixed the problem. (
