Screen is freezes if frequently use Move X+, Move Y+, Move Z+ commands

Screen is freezes if use this commands several times per second even in the document just one curve.

I use these commands as an alternative to NUDGE.

Hi Tatar-

"Move X+, Move Y+"

are these the buttons in the “Organic” toolbar?



Yes, it is.
But i am sorry, i solved this problem. I poorly updated my video-card. I restored PC and commands work fine again.
