I was messing around with an instance of Stylus RMX(1.8d) in Ableton Live 8.0.1 It wasn't a very complex multi at all with only two or three parts. I was switching the time signature of one of the parts in Time Designer flipping back and forth. At some point the GUI turned into a blank page with an image of the box that RMX ships in the upper left hand corner. You could still switch to one of the other pages(Chaos, etc.) by "clicking thru" this blank image. Those pages displayed and functioned normally. The only way to restore the Time Designer page was to close out of RMX's property page and reopen it. But! as soon as you tried to adjust a parameter in the Time Designer page the box ghost image would reappear and render that part of the plugin unusable. FWIW- I built some more complex multis in 1.7 without any issues. Any thoughts?
