	OK, i friged around with it and found out what the problem is
(more specifically).  It turned out that it occured regardless of whether
the screen saver was running.  I use a program I wrote to change the text
resolution.  If I remember correctly, there is a bios call to change the
font used, and one of the parameters is the height of the characters and
the number of characters to change and a pointer to the buffer containing
the bitmaps of the characters.  I tell it to use a height different than
16 (the default for 80x25) and I pass it a buffer of Zero characters.  I
usually use 11 pixels high.  This just chops the bottom of the characters
off in DOS and displays about 33 rows or somehting.  In a Win95 box, this
just adds lines to the bottome of the window.  I've used this program for
a while and I've never had any problems with other software, but when
SetEdit tries to re-initiate that mode, it crashes the DOS box, especially
if it was running in 94x34 mode.  If I don't use my program to change the
resolution, then SetEdit never crashes.
