Okay I just now began using VEP7 as I have been out not been using any of my audio stuff.
Tonight, or a few minutes ago I loaded up REFX Nexus 2 and Omnisphere 2 into VEP 7 because I created a new sample program for my Korg Kronos X that I am going to sample using Autosampler 2 that I purchased years ago before Redmatica sold us out to Apple. Yes I am still on El Capitan and won't go up because of this one reason because I just love my Autosampler 2.
Anyway, I noticed in VEP7 if I use the integrated FX, and open those windows, and switch back and forth between VEP7 and AS2 it doesn't make a difference if I close the FX windows in VEP7 before I switch to another window in OSX whenever I come back to VEP7 the integrated FX plugin I had just closed, not disabled but the FX PLUGIN WINDOW only is open again, then behind that windows is some other WHITE out window I cannot even see what they are..Some kind of bug going on like its always trying to go back to last window that was there previously but its a white window but its also showing the Integrated FX Plugin Window.
This is in OS X with El Captian using 750TI Intel i7-4770k 16gb memory...Never had any issues before with VEP5...Something with the integrated FX windows. OS X 10.11.6 El Capitan...
