Could you please try to use key commands instead (i.e. instead of clicking on the nudge buttons)? On Windows, the key shortcuts are:
CTRL + Right Arrow Key (nudge right)
CTRL + Left Arrow Key (nudge left)
I’m suggesting this because I think you might be dealing with a video driver issue.
After testing the key shortcuts, I suggest you add your system information to your profile. This can help you receive better replies to things/issues you post on the forum… Learn how to add system info to profile by accessing the following link:
