MODE32 users should be absolutely certain to install the new MODE32 version 7.5 from Connectix (see TidBITS-243) before upgrading to System 7.5. We have it on good authority that installing System 7.5 on a non-32-bit-clean Macintosh with an earlier copy of MODE32 (or perhaps Apple's 32-bit Enabler) may cause severe damage to the system software, necessitating a complete reinstallation. Also, MODE32 7.5 is compatible with System 7.1, should you not have upgraded to 7.5 yet. [MHA]
Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
