Controls Key Problem ( White DOS command list )

[K_Freddie]

It might be your Windows 'Accelerator' key settings.. one I know is the shift key - you press it for more than 5 secs or to many times windows will exit the game and go in what I think is 'macro mode'.

You'll have to disable this feature in windows.
Can't remember how to do it.

I was thinking the same but i don't press Shift fast as you say, I press Shift
randomly and not 5 time in a few second. I'll try your solution anyhow and write the result.
Thank u anyway
