... at least that's what I get from searching the regular Fitaly Forum for Jot. Take a look at
this message. (I don't need / use Jot myself.) OTOH there is Dennis's mail in this thread with the same problem as your's. My guess for a possible reason is an unfortunate order of activation of both programs. I tried an explanation in
this message, Jean posted a more colourful explanation as a followup.
You wrote that you used the .prc-version (stand-alone) of FitalyStamp, so a first try may be to switch to the hack-master version. If this doesn't work, you may try different orders of activation (or perhaps even installation). Best way would be to persuade the makers of Jot to accept the de-facto-standard of HackMaster and offer an additional variant of their program which can coexist with others (that patch the same events).
HTH - and please report back if you succeed...
