[IDV #ZEO-881615]: Screen Capture and Other Issues

Hi Stefan.

I too have a Mac and use an external display in extension mode (i.e. I can 
freely move the mouse and windows to and from each display).

Unfortunately, I cannot reproduce this bug. I displayed RUC data in the map 
view on my external monitor and moved my dashboard to the laptop. The image 
capture worked fine.

Out of curiosity, does this only happen with the IDV is "split apart"? What 
happens when you are exclusively on the external display?
