TGuitar VST very small display


the control panel of Tguitar is very tiny on my high resolution screen. As I see in the tutorial (2) TGuitar from Acoustic Samples Walkthrough | VST Instrument for HALion - YouTube (see the screenshot below) there must be a possibility to zoom the control panel, since the panel is much bigger compared to the list of midi channels on the left side, than it is the case on my screen.

Does anybody know how to adjust the zoom?

Thank you very much in advance

There were some bug fixes for TGuitar. I would download and install the latest version of TGuitar from Steinberg Download Assistant to see if that helps.
