Have you tried resetting the workspace? A different workspace?
Hi Peter, no, I am not familiar with that function.
I think the workspaces Peter referenced were introduced after CS2, but I no longer have it installed to verify.
On an off chance, have you hit the TAB key with nothing selected? THat may have hidden all your panels and toolbars.
edit: or is the Tools option in your Window menu enabled or not?
edit2: or it could be that the workspace command just became more readily accessible with recent versions... ^_~
Window > Workspace... and in the next menu you'll be able to choose a different workspace, or down near the bottom you should also see a Reset <Workspace Name> command.
Man, Peter. That did the trick. On my CS2 version, Workspace is at the top right under Arrange. There were three options: [Default], Save Workspace and Delete Workspace (which was grayed out). I tried [Default] and, bingo, Tools reappeared. Thanks so much.
