Virtual Prime on MacOS High Sierra, crashing and menu text vanishing

[JDW]

I've been running, or trying to run, the Virtual Prime simulator on my 2015 15" MacBook Pro and on my 2009 27" iMac, both running MacOS High Sierra 10.13.5 (newest as of July 2018). I even tested this on my late 2015 5K iMac at the office and found Virtual Prime to have the same problems -- that iMac also runs the latest High Sierra OS.

The Virtual Prime app launches fine and works fine at first, but when I switch to other apps like Safari, doing something for a while, then switch back to the Prime app, strange things occur. The biggest problem is that text in menus vanishes in a seemingly random way. Consider these screenshots:

After switching away and then back to Virtual Prime (menu text missing):

After freshly launching Prime (no problem):

And whenever I quite Virtual Prime, it quite nearly always crashes. The only time it usually doesn't crash on Quit is if I freshly launch Virtual Prime, then do nothing except to immediately Quit. But if I launch the app and click Home and type 6*6 ENTER to get 36 and then Quit, Virtual Prime will crash and throw up the crash reporter dialog.

So it's a mess of crashing and menu text vanishing that makes Virtual Prime almost unusable on 3 very different Macs (which proves the Mac hardware isn't cause it) running High Sierra with boot drives being SSDs and formatted APFS. I just ordered 2 Primes, so I hope the actual calculators don't crash like this. Even so, I would be interested in working with HP to resolve this issue so I can actually run Virtual Prime on my Macs in a usable, crash-free, pristine menu way. Please tell me what other information is needed to achieve that.

And if any of my fellow High Sierra Mac users are reading this (High Sierra running on computers with SSDs and therefore using APFS formatted drives), please test Virtual Prime on your systems and report back here to say if you see the same things I do.

Whatever help you can suggest or provide would be greatly appreciated. Thank you.
