APPLE - TAB - switching between programs
I'm having issues more and more with the 'finder' in that switching between programs doesn't actually switch properly.
For instance, I would tab out of a program, hit apple-Q and the program that I tabbed out of would close.
I have the same issue when clicking on different windows - for instance I click on a abrobat window and start making changes, but the menu bar at the top of the screen is still stuck with InDesign.
I have the same issue when using multiple programs at random, I just had a notepad open and couldn't switch back to adobe to copy text back in - no amount of tabbing or selecting the program would actually take me back to acrobat.
Any ideas? Is this just one of the joys of working on a Mac or do I have some kind of virus?
Many thanks!
