OldUnreal (Engine)

my dad has a weird mouse bug on unreal,he can aim to all sides normaly except for the right side...
if he turns his mouse to the right it go's slow and very shakey(just the mouse not the rest of the game)
help plz?

Oh look. someone else with that bug. Smirf cant reproduce it to fix it fully but there's two ways to fix it.

alt+enter until it refullscreens a few times until it works, or type your current resolution in setres in console.. ie if your resolution is 1024x768

setres 1024x768

thx for the fix,it worked
