I don't know if this bug was fixed.
Windows Vista x64, SP1
Several times now, when I have gone to print, it looked like nothing was happening. I realized that the Save As prompt was behind all other windows, and I had to Alt-Tab to get to it.
It didn't appear on the Task Bar, and it obviously didn't pop up in front of the application I was printing from.
Is this a known issue? Has it been fixed already?
Having the Save As dialog appear on the Task Bar or having it make sure it is the top-most window would help.
