If you see an “out of memory” message, try turning on Temporary memory (in the Preferences dialog).  If you still are running short on memory, try increasing Tex-Edit’s memory allocation in the Finder.  I would suggest at least 1200K if you plan on displaying large color pictures or playing movies.

If you notice any strange behavior while using Tex-Edit Plus, try deleting the “Tex-Edit+ Prefs” file in the Preferences folder.

Some problems are caused by Extension conflicts.  Try re-booting your computer with the shift key held down.

Some problems are caused by a corrupted “Desktop” file.  Try re-booting your computer with the option-command keys held down.

If you have trouble with the speech functions, try increasing Tex-Edit’s memory allocation slightly.  The “high quality” MacinTalk Pro voices use the most memory.  “Marvin” and “Fred” use the least.  Re-installing PlainTalk may help.

Unusual problems may indicate a viral contamination.  Try one of the virus checker programs available.

Persistent problems may require a “clean” System re-installation.
