Bug report (v7.03): frozen after sleep

After waking from sleep, the GUI no longer works.  Mousing over the GUI results in visual glitches, and nothing can be clicked (see screenshot below). Pianoteq must be restarted.

This occurs when using an external audio interface. 

With previous versions of Pianoteq, upon waking Pianoteq was unable to find the external audio interface, and would pop up the dialog box shown in the screenshot -- which I suppose was a different, smaller bug -- but the program still functioned. 

Mac 10.15.6
Intel Dual Core i7
Pianoteq 7.03

Thanks for taking a look!
