Program freezes when going to Preferences

bug

#1

While modeling I noticed SU 2018 freezes when I go to Window> Preference. My mouse no longer responds and I hear a sound such as the one happening when one does not close a dialog box when I mouse click. yet I see no dialog box opened. Also, the whole window very lightly fades away and freezes. I have to go to the Task Manager and close the program to unfreeze.
It starts again fine, but the same issue happens when going again to >Preferences.
Would appreciate any insight. In the middle of a pressing modeling job.
Thanks.

It sounds to me as if the Preferences panel is opening off screen. This would be consistent with what you describe. If you try to open Preferences and then hit Enter, does it unfreeze?

To quote the famous Box,

Well thank you very much, you resolved my issue very quickly. The famous Box remains a mystery to me but is quite knowledgeable.
No doubt I’ll be back.
