wxErlang

I'll try re-installing them when I get home, however I am a little skeptical this is the problem. I have no problems with OpenGL with any other apps or when using Java with JOGL (Java OpenGL bindings).

Note also that when I wrote: 'I have tried explicitely setting the pen and brush to white on the line before drawing (incase it was being lost/not set/overridden/etc), makes no difference.'

I meant: it does work in setting the colour to white, up until the 'bug' occurs and turns all colour to black.


A third problem, if I make the wxFrame and wxDCs in one process, and then interact with them in a second process, the calls fail. I am not at home, but it is something along the lines of 'unknown_port'. Is there any way around this? I would like to be able to render multiple frames simultaneously in separate processes.
