Well I set it to a fixed height, 22 pixels, since that's what it seems to stay at no matter what I do to the XML file.
Side by Side with the tab box drawing it's stuff properly at last.
But now I got a bug to where the pages are causing the entire render chain to fail, background of the editor draws fine but anything in the active UI won't. Think I may be overloading the video memory with how many render targets I was using to clip labels to their boundaries. I'll test that theory later when I have enough time to set up a video memory counter.
Oh yeah, I know the QMark isn't drawing on my editor, that's due to it's not flagged as on in the inventory window. Probably something SoE did when they put in that new help system a few months ago, to flag them on for windows with help available.
