Well, this is a pretty simple issue, that likely has no answer, but it's worth a shot:
Certain Objects like the list object and (in my case) OpenGL seem to always override MMF2's layering system. Although I'm pretty sure I know why, I'm not going to say why I think it is because I know I'll sound stupid if I'm wrong. I'm trying to add HUD over my OpenGL object, so since it seems to overlap pretty much everything, I thought I would try making the HUD on a different frame and using the Sub-App extension, which still failed, even though Sub-App generally overlaps everything itself...
This seems to be very problematic even back when I needed to use the list object behind other actives, but in that case you can create your own custom list object with strings and such, but I obviously can't create my own OpenGL... with strings...
So there's my issue. Hopefully somebody knows how to beat this obnoxious system. If not, than... screw me.
