This will only work if I have not 'surrendered' control, right? I've got currently a script that tries to ease some of the changing of settings for open gl previews, and it calls the actual operator after changing some settings. The problem is, unlike a normal preview, I lose the ability to hit esc (and I would like at least a progressbar) Do you know if I can do this?
