If Pithhelmet is installed, after downloading a pdf and it opening in a Safari window with Adobe Reader 7.0, you cannot select windows in Safari or bring all to front. To see the bug, do this:
With Pithhelmet installed, start Safari.
Open another window
The Windows menu allows for switching between windows.
Open a third window. Download a pdf with Adobe Reader 7.0.1 or 7.0.0 installed and opening the file within Safari.
Now find that the Windows menu does not allow switching between windows. Bring all to front does not work. No checkmark on the displayed window seen.
Closing the Adobe Reader window does not help.
Quit and restart Safari and all is well until the next pdf download.
This has now been reproduced on 3 machines, including one with a fresh install of PH and Adobe Reader.
If anyone else is seeing this, please post. Mike Solomon has been responsive but he cannot reproduce the behavior. Please send him a report if you are observing this.
