What lazarus version are you using? 32 or 64 bit? What fpc version?
Can you try the svn version or at least the daily snapshot?
I didn't try the control under windows recently, so maybe some win32
devel broke it unknowingly. I will try to find a windows machine to
test.

You need a recent lazarus 0.9.25 version to use the openglcontrol
under gtk2.
