The following is from a file found on COMPUSERVE. Tried the portion using
 DEBUG and could not get profix.com to read my prokey files (ex. ws.pro)
 Maybe some one who understand the top part of this message can fill me
 in.  Thanks    John Roswick, Bismarck.

    Keywords: SIDEKICK PROKEY PATCH FIX BUGS COMPATIBILITY BORLAND
    
     Attention Sidekick/Prokey users !  We at Borland were having
trouble getting Sidekick to be compatible with Rosesoft's Prokey and
as many of you Prokey users out there know everything locked up when the
two got together.  The reason Prokey does not work is because it trashes
some of the registers when running and confuses Sidekick as to make your
terminal go down.  Enclosed is the portion of Prokey which does this.

Prokey does not save and restore all registers when trapping interrupt
1C.  The reason why this error occurs at a higher frequency when using
Sidekick is beyond this discussion. However, to verify the error try the
following:
 
1. Start Prokey
2. Define a key recursively
3. Notice prokey now issues an error message
4. terminate definition (fast...)
5. press return 100 times
6. if prokey did not crash repeat step 2-6
 
Register destroying occurs when Prokey is flashing error message.  You must
terminate and press return as fast as possible, and be logged on a floppy
drive (important: let your prompt show the active directory in order to let
dos read on the disk).
 
The following program establishes a trap at interrupt 8 (to make sure Prokey
or others does not overwrite it, bios int 8 then activates 1C).
