Hi, this is a message and suggestion without any urgency, just picking up bits and pieces from various years (!). I think it would be good to move the Windows version of gretl to using gtk3 instead of gtk2, at least as an option, if at all technically possible. First of all I would hope that it gets a more "modern" look automatically through that. Secondly it would be really cool to run gretl in a browser window, as discussed on this list in March ("GTK broadway support in gretl?"), and already back in 2014. Some more background: Six years ago Allin announced ("gtk version in gretl build" in October 2013) that on Linux gtk3 was the preferred framework. Later after version 2017d it was made easier to build gretl on Windows, as I tested myself back then. (BTW, the build appendix C of the guide still does not mention documents like http://ricardo.ecn.wfu.edu/pub/gretl/winbuild/gretl-winbuild.pdf.) That Windows build document does not really mention the assumed GTK version, but the underlying package list http://ricardo.ecn.wfu.edu/pub/gretl/winbuild/pkglist.txt is only made for gtk2 (for example with mingw-w64-x86_64-gtk2). Are there any known problems wih gtk3 on Windows that have been observed after, say, after 2017? If not I'd like to try this eventually, after the summer. thanks sven
