I'm not sure how to phrase this, but I'll try, and it is a minor issue, still it can have consequences...
If I have a floating FX (say ReaEQ) and some other FX (say ReaTune) has focus in the FX window, then enabling/disabling the floating FX from the FX window does not always check the mark in the floating window.
LiceCap here:
As you see, the first click in the enable checkbox in the FX window (to the right) does not set the checkmark in the floating FX window (to the left). The third click does. But then the fourth click in the (right) FX window should disable the checkmark also in the (left) floating FX window, but does not. And this seems to follow no regular pattern, sometimes it works, sometimes it doesn't.
Clicking the checkbox in the (left) floating FX window works as expected, but something is not right when clicking in the checkbox of the (right) FX window.
The floating FX does get enabled/disabled, it is just the GUI that does not show the right thing.
