Tools are very small

I am on Nuendo 10.1 with Windows 10. When I engage a tool it is very small. Is there any was to fix this? Also when I load a SoniVox vst plugin all of Nuendo shrinks. I hope there is a fix for these issues. Thanks.

That happened to me too…
I have to LOG OUT from WINDOWS and log in again… try that.
