Currently we have to solve a lot of issues with windows gdi handles required by the gui. It seems using gtk3 increased the number of this handles by a large amount compared to gtk2 (for whatever reason) and there also is a maximum of gdi handles per application on windows (10000). Using SETM (Single Editor Tab Mode) that is not a problem, but using METM (Multiple Editor Tabs mode) RT runs out of gdi handles very fast (e.g. open 10 or 11 editors) and crashes.
I’m already working on reducing the handles by removing obsolete gui controls and solving gdi handle leaks.
When that work is completed, we can think about adding new tools.
