Hi,
The TGuitar being the first library we coded for Halion, we thought the size did not matter 
It turns out on smaller screens or at least at smaller resolutions, it goes out of the frame, we were able to experience that now that’s we’re quarantined and don’t have our nice retina screens.
So we’ll issue an update that will fix this don’t worry and probably just reduce the size of the interface by 3/4 or something like that (or maybe just offer a half size preset), it just might take a bit of time because we unfortunately don’t have our dongle that is at our main office and we can’t go there… and ordering a new key might take a bit of time given the current situation.
Regarding the freeze, can you give me a little more information, does it happen when it sits idle or when using it (heavily or not)? Does it freeze with maybe weird sounds coming out of it (this could be a script error)? We have been working for hours on it in standalone and it never froze… Are you using the latest versions of the halion softwares?
