After the Manchester update the white screen during launch was much improved.  Now that I've moved to Newburyport, they're back with a vengeance!  Not just parts of the GUI but the whole screen goes white.  I'm also seeing that the improvements in "Copy / Paste" and "Clip Gain Envelopes" have evaporated.  I guess I'll roll back to Manchester.  Any suggestions would be greatly appreciated.
