I have a small problem which I cannot fiqure out at the mo' so
I would like a little help from you DJGPP veterens.

basically I am using near pointers using the __djgpp_nearptr_enable(),
I malloc some abitary memory usually less than 30K for a temp buffer
the pointer is a global pointer. the problem comes when I a try to
access the memory from within my mouse interupt service rountine
I get a segmentation violation, is there any special operation I need
to carry out in order to access this mem during an interupt???

thanks for any feedback
Simon
