Why do you modify the use of the >system global page? TIC does not modify the ProDOS global page except via MLI calls Alloc Interrput and Dealloc Interrupt. ProDOS itself modifies the global page when interrupts are used. Perhaps your clock driver install program depends on undocumented entry points in the global page that get changed when a program that follows the rules installs an interrupt handler? Maybe there's some other sort of incompatibility problem but TIC doesn't directly modify the global page. I've changed a few things in the way TIC initializes itself that will appear in the next released version (3.00) and Applied Engineering's version of the program, DataTerm, already has these changes in place. Maybe these will help with your problem.
