Dane Summers successfully answered Rich Collins's question:

At least once a day, OS X Freezes when I Command-Tab.

The application switcher comes up, the selection box is over an application I can move the mouse but that is it. I have to restart every time this happens. I will pay mucho to get this working.

*Update*

I found this person with the same problem:

*Update*

I already upgraded to 10.4.7

*Update*

I already tried to repair file permissions

*Update*

This happened on my PowerBook, and now it is happening on a "fresh" install on my new MacBook. Here is what I am usually running:
* TextMate
* FireFox (Have a hunch this is it for some reason)
* X-Chat
* Terminal
* Mail
* Adium
* SSH Keychain
* iTunes

Is Firefox sucking up a lot of memory? Are you browsing sites that have a lot of ads?

Many recent banner ads, especially those with lots of Flash or other interactive technology, cause memory leaks in Firefox. I typically have to shut Firefox down and sometimes reboot my whole computer after a few hours of browsing ad-heavy sites.

Try an extension like AdBlock Plus at https://addons.mozilla.org/firefox/1865/ to stop banner ads from loading.

OK I will try that next. Right now I am trying out a change that someone else suggested. No crashes yet, so I don't want to confound the experiment.
