Ultimately I'd like to report a bug regarding font usage. When opening "qmc2-mame.exe", the default font is chosen instead of the one used in the configured style sheet. Going to the "Options" and clicking "OK" however fixes that. This has to be done each time "qmc2-mame.exe" is opened. It happens under Windows 7 SP1 x64 on version 0.56, but I guess it applies to the other Windows/QMC2 versions too.

I know the bug is of minimal importance, but it's still worth the report IMO.
