Problems switching between fullscreen and windowed (Hotkeys problem?)

[SLAYER]

It works at the beginning, but after playing for a while it's impossible for me to switch to windowed from fullscreen or vice versa. Escape (stop) and F9 (screenshot) also have the same problem.

Playing: RE0, RE1 (GC)
Core i7 @2.6
GTS250
6gb ddr3 1600
DX, VC, drivers are up-to-date
currently using r6837 and r6898

I can post my settings if you want, although they're the same as the the ones in the RE thread

anyone having a similar problem?

are you running with the frame limit uncapped?, usually it does this because the interface input becomes lagged behind the actual result for up to 30 seconds.

Framelimit is set to Auto.
I tried using other values, still the same.
