How to make RPGM games playable with mouse?

[NeonSelf]

Every button response happens only after double click, since first click selects the button instead of using it.
These games rely heavily on multilayer menus, its frustrating to keep making doubleclicks all the time.

Are there some settings to make RPGM work properly with mouse?

 

[Meaning Less]

For RPGM I recommend ditching he mouse entirely, the engine wasn't really made for it and even the games that support it are often clunky as you noticed.

-Move with arrows
-confirm with enter
-menu/cancel with numpad 0
-run with right shift

That will allow you to play most rpgm games one handed easily.
