--- Comment #5 from foobard jens@porup.com 2008-04-15 14:23:39 --- Created an attachment (id=12212) --> (http://bugs.winehq.org/attachment.cgi?id=12212) windows screenshot of Acrobat clipboard
Here's a screenshot of what the Acrobat clipboard viewer looks like in Windows.
I had an unexpected and rather bizarre experience taking the screenshot -- hitting Alt-PrtScrn repeatedly caused the captured image to be recursively (and immediately) pasted into Acrobat Pro's clipboard.
Uneducated guess -- Acrobat Pro 6 is working directly with the Windows clipboard. It's the only thing I can think of that would explain this odd behaviour.
