Strange gtk 1.2.10 behaviors with nano-X

Searching the mailing list, changelog, and google give indications that gtk 1.2 is/was working with nano-x.

I could not find any actual instructions, like you made for fltk. :-(
I have gtk compiled against NX11 and nano-x from this git page for armv7.

Tried a number of gtk programs with similar issue.

Any movement of a gtk scrollbar, or hitting enter in a multi line text widget freezes the gtk app. The nano-x window is stll movable, but have to kill the gtk app from a terminal.

Most other widgets seem to work fine.

Compiling same gtk stack against X11 works as expected.

Are there instructions for configuring gtk 1.2 to work properly with nano-X ?

gtk 1.2.10 was configured as : ./configure --disable-nls --disable-glibtest

Tried 2 different tarballs for gtk 1.2.10, same outcome.

Start by reproducing the freeze with the reported nano-X configuration and a GTK 1.2.10 application using a scrollbar or multiline text widget. Compare the same programs against X11 and inspect the relevant nano-X/NX11 and GTK integration paths; done means identifying the cause and documenting or correcting the configuration or behavior.
