X6 Mac issue that CA support can't figure out - anyone else having this problem....

[pdre629]

I am using the full version of X6 on Mac. I've been on the phone with CA support a couple of times and they don't know what the problem is. I thought I would ask here. By the way, this problem does not happen on my daughter's Macbook.
When I open a file and go to Save As, the program makes a "doink" sound when I click on it. It's like the Save As box is open but doesn't have the focus. We've tried minimizing windows, viewing all windows, etc.
I can Force Quit, open CA again, and the Save As button might work that time. Open another file and it locks up again.
Yesterday I tired to print a layout sheet to PDF and it did the same thing. It was like the PDF dialogue box was open but did not have the focus.
Any suggestions? Thanks in advance!
