Windows

Any application crashes when i try to OPEN or SAVE AS, an option who requiere OPEN DIALOG BOX to choose a file. Some apps display FAILURE with COMDLG32.DLL, Office product dosnt have problems, they use another Open Dialog Box.

just curiously, that happens only with my session, but if I log in windows with another account, there is no problems.

So i need to know how fix this, maybe in the registry.

Pentium4
Windows XP Pro, with SP2 in SPANISH
My COMDLG32.DLL version is:
6.0.2800.1106

maybe something is not loaded in my session,
