My program rand just fine with the -pg switch,its when i 
REMOVED it when i was done and recompiled it that i saw
the problem....and it affected other djgpp programs that
WERE NOT recompiled,just ran,which really confused me.
It wasnt till i removed power from my boxand _then_
rebooted that everything returned to normal...  

I will update my files if i can,and maybe later try
profiling again....Let you all know what happens.

BE cool,
 Krogg
