Hi Seppy,
With W10 theme set to 'Light' buttons are visible (attached screenshot). This shouldn't be hard to fix given the software project files. If needed, I can have a go with fixing this issue.
Also, from usage perspective, I had trouble to switch between DMM screen/plot/combined display form - now I understand that it is controlled by click and window proportion. Is there any brif help/FAQ for the app available?
Best regards,
