I tried to open the Pool and it “appeared” that it would not open. I went to the Audio Menu selected Open Pool, nothing, I pressed CTRL-P and nothing. I thought the Pool was broken, but after digging around, I realized that the pool window opened behind a VST window that was open. I would have thought that when a new window was opened, it would be the topmost window instead of hiding behind something else that’s open. The “ALWAYS ON TOP” option on the plugin is on but the Pool should have found another piece of screen real estate to show that it was opened.
If there is an “Always on Top” window and some other window opens behind it (completely hidden), then it’s hidden. The “Always on Top” means “Always on Top”, so no other window hides it.
