I usually find as long as the "yellow circle thing lights" up,it means your mouse pointer is in the right part of the GUI,to make an adjustment,and don't really feel its that big a deal I spose.
When I couldn't get a 64bit version of the Kramer Tape to show up for 2 days,I got a bit spun,but Waves support was right onto it,and it turned out to be a registry deletion needed to be done for that.
The only other thing Iv'e had was sometimes when control clicking to duplicate,I would get NO GUI,but THAT has stopped happening now.
I guess as its still only a year or so,I'm just still so amazed all this stuff works as well as it does,to be too freaked by it too much?
