Couple of bugs using with Bandlab Cakewalk

Working through the tutorial and having much fun. Just a couple of things:
I can drag a midi clip from Scaler into a midi track in Cakewalk just fine. But then, when I select the clip in order to drag it to exctly the correct bar, it leaves a copy behind as if I’d done Ctrl+drag. Not always, but often.
The other bug is when minimizing Scaler within Cakewalk.On a couple of occasions now I’ve clicked restore and Scaler gives me a completely white window. This requires a full restart of Cakewalk to fix. It will allow a successful Save Changes, however.
Running latest versions of CfB, W10, Scaler 2, RME Multiface, Akai MPK mini 3, number of free vst plugs only.
