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
