This behaviour means that there is no preemptive multitasking - the 
MiNT scheduler does not work. In previous MiNT versions (before 1.16) 
the scheduler was hooked onto the VBL interrupt. This was changed to 
the 200Hz timer, because not every machine generates VBL (e.g. Milans 
don't) while 200 Hz timer is AFAIK, everywhere available.

Just check if you don't load anything, that grabs the 200 Hz timer 
vector or resets it to default BIOS state (pointing to ROM).
