This question has been previously discussed here but I can't figure out how to participate/follow-up without answering, so i'm resubmitting as my problem:
I'm a graphic designer using Mac Power PC G5, OS 10.4.11 (system software is up-to-date) & am not using Spaces. (FWIW, before becoming a designer I did Mac tech support for 6 years (back in the OS 7--> OS 10.3 days))
Currently I have 5 applications open (including the Finder). I routinely use cmd+tab to toggle through open apps (i.e. InDesign-->Photoshop-->Mail-->Firefox, etc).
I have no problems switching between applications and their active windows. For example if I cmd+tab from InDesign to Firefox, the active Firefox window comes to the front (even if I have, say, 3 browser windows open).
But when I cmd+tab the Finder no windows come to the front (there are currently 5 finder windows open so i know they're there -- i can see by hiding all the windows or through the method described next).
I have to cmd+tab to the Finder, THEN cmd+tilde (key to the left of the 1 key) to toggle through the open Finder windows.
Per this thread I trashed the Finder prefs (user/library/preferences/com.apple.finder.plist) and it fixed the issue for a few days, but now I'm back to the same problem.
A seemingly minor annoyance but one that really slows me down/irritates the heck out of me.
