TSM Fix is included in the MailFetch package for those users who want to use MailFetch’s option of notifying you when you have new mail, using a floating window. Floating windows often don’t respond correctly to mouse clicks unless this extension is installed. To install TSM Fix, put it in your Extensions folder and restart. If you aren’t using the option to be notified of new mail with a floating window, or if you are using AOL 2.6 or 2.7, (which don’t support MailFetch’s Auto-AOL session execution, which makes scheduling impossible and new mail notification irrelevant), then you don’t need TSM Fix. See the MailFetch Manual for more information on scheduling and new mail notification.
As you can see in the TSM Fix ReadMe, this extension was written by Matt Slot, not by me -- Karl Bunker, the author of MailFetch. I have used TSM Fix in connection with several other programs, and I have never heard of it causing a problem on any user’s system.
