Also im not sure why but i see in the plugins browser it's placing the TAL-U-No-62 synth as an effect, im guessing it may have audio inputs also perhaps so it's getting confused with the listing maybe.
If you are in Capture Keys Mode then on thesynth panel editor go to open program etc it does not cancel the capture so you cannot type text, maybe it should temp disable it until your back to a playing state in the app.
If you right click to hold a note too far to the left it holds the wrong key (not end one), doing this on the right triggers no held notes as expected though so it seems to be the left only. On testing with a not full window it happens always maximized on my large monitor it still happens but only nearer to the keyboard.
hope this is helpful, thanks
