Hi everyone -
Some time ago I started work on a tsr written under TP 7.01
with the help of OpInt/OpTsr.
Now I'm running out of conventional memory (main applications
loaded after the tsr are hungry - about 550 Kb).
So I decided to convert the module into a _swappable_ tsr with the
OpSwap1/OpSwap units.
Started out with the short example (BEEPIT) shown in chapter 11
of the manual.
Almost everything went fine (besides a few hickups in the learning
curve)
until I added the "OpEnhKbd" unit to the list in the "uses" clause.
This resulted in (non-reproducable) errors crashing the DOS system
and requiring a cold boot every time.
This crash seems to happen once the procedure "StayResSwap" is called.
(OpEnhKbd was used in the old tsr without problem).

Does anyone have had a similar experience or even better a remedy??
Any suggestions how to proceed much appreciated.
