Blank dialogue box I cant get rid of and does not let me interact witht the software

Anyone had this yet? Just fired up VST 3.0.12 and got this blank dialogue box that sais nothing. Clicking the X does nothing. Clicking the tick box just ticks or unticks it. Programme still responds to key commands i.e. space bar will start a track.

OK found it - weird one. Tested on a couple of releases of VSTL3.x. If you have inactive plugins it brings up a dialogue box at start - if you click ‘cancel’ this thing comes up for me. I think its an incorrect rendering of the ‘dont show this again’ box.

… which Windows version are you running?
… what happens if you select “Menu / File / Preload…”. Do you see a dialog? Which color?

Thank you
Michael.
