Minimize extension sets to reduce Classic conflicts

As part of installing OS X, I upgraded my Mac from OS 8.6 to 9.1. When I first booted into it, most fonts displayed improperly and none of the icons displayed on the Desktop, making the system virtually unusable. Bad.

I eventually had the bright idea to boot 9.1 with the "base set" of extensions, without all my customizations that were there before. Then I started added back in the extensions I really cared about a few at a time to find the buggy one (I haven't found it yet-- I've been exploring OS X instead. :).

I believe to accomplish this I booted into 9.1 by holding down the shift key to disable all extensions, and then used the Extension Manager Control panel to revert the extensions to the "OS 9.1 base set". After another reboot, things looked normal.

[Editor's note: Similar tips have appeared over the last six months, but it's important enough to repeat. If your Classic environment is not behaving as expected, check the extension set. You'll want to boot with the bare minimum required to support the apps you use regularly in Classic.]
