I wrote a decent sized chuck of code on Vista and I recently upgraded to  
win 7. However despite everything being installed to the equivalent  
directories it instantly spits out a ‘couldn’t find fox 16’ error. I’m  
fairly new at all this so I wouldn’t be surprised if its some obvious  
thing i overlooked/dont know about. Does anyone have any ideas? I would  
be most grateful.
