macOS Modifier Keys with TeamViewer

[JohnEeeDee]

This is an edge-case bug, but thought I'd report it. We use TeamViewer (Mac to Mac, no Windows involved) and when I'm controlling a macOS machine running VirtualBuddy, the keyboard modifier keys (Shift, Option, Command) don't make it through to the VirtualBuddy VMs. They work fine on the host, but the VMs don't see them down, so you can't even type a capital letter on the VM.

Strangely enough, it works fine when controlling the host machine using Apple's Remote Desktop app...it's only when controlling it via TeamViewer that the modifier keys are broken. I'm guessing that TeamViewer must use some other mechanism of sending modifier key-down status that VirtualBuddy is not recognizing.

Since it all works fine when remoting in with ARD, it's not a VirtualBuddy or VM setting, and TeamViewer works fine with other virtualization apps like Parallels, so it seems to be something specfic between VirtualBuddy and TeamViewer.

Have you tried changing the "Capture system keyboard shortcuts" setting before starting the VM? Does it make any difference whether it's on or off?

My apologies, I meant to mention that I tried that setting in both On and Off states, but the symptom (with TeamViewer) is the same. Since it works fine with ARD remote access, I think it's probably something weird with the way that TeamViewer sends or interprets modifier keydown signals.
