I routinely forget that ProAnimator still has a little quirk if you don't have the panels docked in AE that you get some weird processing slowness an inability to use the plug-in properly without switching between other programs and back to AE.
Is this an issue that can be fixed in the next release of ProAnimator?
I have two monitors and I usually have the Render Queue panel and Info panel on the secondary monitor. For the time being I just set up another workspace preference and activate that, when I know I will be working in ProAnimator plug-in. This tends to work.
