No, but I am using TrueVision3D on a wxWindow. I've tried parenting the dialog to the same panel that the wxWindow is on, but I've also tried parenting it to the frame and indeed to null but all sorts of completely random events seem to affect whether it ever shows or not.
I'm pretty sure it's not popping up and vanishing, because program flow does not stop. The dialog is returning wxCancel or whatever to indicate that it's finished acting. I can only assume that it's sending wxCancel because it believes it cannot open for some reason, but I have no idea why that would be. 12 categories in a property grid instead of 11 is not, to me, a valid reason, but that's definitely one example of something which stops it from popping up.
Still, if the GLCanvas does weird stuff too, there might be a connection. I'll see if I can't rearrange the location of this window somehow and maybe I'll make a difference.
