Many thanks for the tip about 64 bit. Done.
Sad to say though I still get the mini-sized presentation for a lot of the plug-ins. A lot of them, not all of them, pop up with a small icon of the plug-in and a window message saying ‘No plug-in screen shot available.’ It does allow me to switch to a text based editing format of the plug which I don’t find handy at all.
If I hit the ‘click to edit’ option a sort of veiled grey screen drops in separating the image of the plug from the rest of Cubase which is unedifying because the editing now takes place ‘outside’ of the main Cubase environment.
This all began after importing old Cubase Studio 4.5 files into Cubase 6.5.1. Do I need to think about uninstalling and starting over?
God I hope not.
