Black Window on .Net app popup windows

I am trying to run a windows business application that was written in .Net. the main window opens and seems fine. but when it opens up a secondary window. its filled with a black box. If i quickly resize the window i can see the application "behind" the black box around the edges. It looks like a rendering issue. I am new to crossover not sure what to check, I did test this same app on a Linux PC and it works without the black window issue.

forgot to add...
