in circuit emulator problem

I have a situation where after performing a halt and re-going on the
ICE I am using, one of the interrupts effectively becomes disabled,
ie.. its like it has become masked, however I have checked the
interrupt mask afterwards and its still intact.. And its only one
interrupt which is being affected. Maybe a hardware issue.. Its an
older system so who knows. Any help appreciated.

Thanks in advance,
Slavko
