I have been sent an issue by a user who has occasions when the GoView is blank with a red diagonal cross.
I doubt it would be an installation issue.
Yes, it’s likely to be a GDI+ problem. Identifying it might be difficult though. We’ve had years of experience in tracking down obscure GDI+ bugs and incorporating work-arounds into GoDiagram.
It would be good to narrow down the kinds of objects that are being shown when this happens.
Do you override Paint anywhere? Do you do any drawing or filling at all?
