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

Stefan,

Thanks for your analysis. It is good to get it in the record.

I actually do not think it has anything to do with IDV. What is happening is at 
a lower level in the software stack, perhaps at the Java level or probably at 
OSX graphics level.

What issue do you want to tackle next?
