Hi I am having some problems when I come to try to set Dosbox to opengl or ddraw.

I have two monitors one running off a 3DLabs Oxygen VX1 the other off a S3 Savage4 PCI. If I try to run dosbox on the VX1 then it crashes in ddraw or opengl - the screen temporarily goes black then dosbox closes down.

So I changed my primary adapter to be the savage 4 - theroetically a worse card. In ddraw dosbox works fine. This is the really wierd bit - In opengl if the shortcut I double click on is on the VX1 screen dosbox will work fine, if it is on the savage 4 screen the screen is all covered in coloured squares!

Any ideas how I can get dosbox working with the VX1 and why the shortcut location should matter?
