Switch user screen flickers

[Gambler FEX online 0]

When I press windows-key + L and enter as another use, the screen flickers like it is changing the res. Ok if I had different res between the two users, but I dont. I have the same 1152@32bit in 100Hz on both users.

 

So why does it flick the screen?

 

System info:

 

Elsa gladiac geforce 2 (21.83)

Asus P2B-DS

2x P450

GTXP

[savtronic 0]

and that closed my connection in the same time

 

HHeeeLLLPPP !!

 

Thanks
