Hi,

I posted earlier about having problems linking opengle and dlls, but
now that is fixed  (Thanx for your help!). =A0However, now my code runs
without error, but no display window opens. =A0I have transfered my code
to a lab-mate's computer and it runs and opens a display window, but
mine does not.
