I normally have Ctrl+F set for Isometric view, but now it doesn't work after upgrading to SW2004 SP1.0. Whenever I try to assign it (Tools-Customize-Keyboard-Others-Isometric), I get the message that it has already been assigned. However, I have gone through EVERY command in the available list and Ctrl+F is nowhere to be found. Any suggestions short of completely re-doing my hotkey commands?
