extrude error

Hi,

I'm trying to extrude one surface, but i have a problem that i can't see the 'OK' button, so in fact it doesn't let me do anything.

I tried to change my windows resolution, but it didn't influenced flux resolution.

I tried to scroll down in many ways, but it didn't help as well.

someone has a better idea how to solve this bug?

thanks;

Omer
