     Wolfram,
     
     We have no problems with the distribution of the MPLAB-SIM 17C4xx 
     updates.  People should note that these are what we call "dot" 
     releases, software fixes that are not as robustly tested as our full 
     release.  Unfortunately the timers were not re-tested after some minor 
     changes in the last release, so this bug slipped out.
     
     If anybody else would needs advnace copies this software, I'd be glad 
     to privately mail the software.  We'll post it on the 'net and BBS 
     next week. Note that you *must* have MPLAB v3.12 to use these drivers.

Callum,
     
there is a bug in the simulator software for PIC17C4x since some MPLAB 
releases, that prevents timers from working correctly.
I already told Microchip the problem, and they sent me a fixed version 
of MPLAB-SIM for 17Cxx in private e-mail (for MPLAB-version 3.12).
I will send you this package in private eMail (I hope Microchip 
won't blame me for that!).
     
regards
     
Wolfram
