In response to my own note...

Two wise persons have mailed me to tell me of the problems with
TextEdit and the growing textedit records/linestarts array.
Sure enough, the handlesize of the textedit record in question
is growing 16 bytes for every insertion of 8 lines, as expected
by a corresponding change in the linestarts array.  So, I
speculate that the cause of the program locking up is:
When TransEdit calls TECalText, it attempts to SetHandleSize(),
cannot find the necessary memory and hangs (or my program does
not check some error condition and it is my fault it hangs).
I am not intimately familiar with SetHandleSize(), but it seems
that I may be able to place the TextRec in high memory or something
like that to avoid this problem...

Any further comments/suggestions ?

Thanks very much!
