After losing several days worth of work on a ThinkTank 512 outline I called 
Living Videotext and found out that their current version of software
(1.2) has a SERIOUS memory management bug in it that causes random crashes
and screwy characters to show up in the outline.  In addition, it is a creeping
death sort of problem, and you can go through several saves accumulating these
garbage characters until it gets so bad that the tool crashes.  The problem is 
worse on long outlines (I havent seen it on outlines less than 10K in size) 
and occurs *ONLY ON* macs with the 128K ROM.  I have not seen problems on my
(work) machine with the 64K ROM.  It occurs with either the old or new System 
and Finder combinations.

Another note, TT512 doesnt work with anything that takes up any memory at
all, as nearly as I can tell.  DO NOT turn on the RAM cache, use switcher,
and it is probably best not to use anything else that consumes memory
(e.g. JCLOCK.)  I note that the SIZE resource says 491K is the minimum
memory size...

Would someone out there *PLEASE* put me out of my misery and do a real MAC
implementation of this indispensible tool.  TT does virtually nothing at all
like good mac software should.  (e.g. no scroll bars, screwy text editting,
evidently does its own memory management, is HUGE for what it does,
is incompatible with almost anything else such as switcher, etc. etc. etc.)

In defense of Living Videotext, however, the person I talked to there was
very knowledgeable, helpful, sympathetic, and honest.  She also didnt have
a workaround other than to keep the outlines small.
