of course .
the inptrrupts work any way in micro controllers and micro processor." if you didn't mask them"
when your code has a problem and you have an bad loop or you have a bad jump in your code the micro will hange. so if you want to use whatch dog you must use in on your main code (never use Watch dog command in ISRs).

hai
what do you mean by hanging?
if it means exicuting a task permanently,then it's not called hanging
this time it's performing a work
and this time it will ready to service all the interrupts
normally 'hanging' means the microcontroller stop all working and need a reset or on/off to start the controller. this time it will not service any interrupts
