Hi it turns out this has nothing to do with dillo but a [transient] entry in the fluxbox 'apps' file takes care of it https://fluxboxwiki.github.io/category/howtos/en/Editing_the_apps_file.html http://fluxbox.org/help/man-fluxbox-apps.php right clicking on the dillo 'save page as' title bar and 'remember' options sets it up
see attached pngs
1.png 'save page as file' dialog - dialog size i want
2.png 'save page as file' dialog - file already exists - dialog size i want
3.png 'file exists' dialog - is the same size as 'save page as file' dialog - the size is to large for what i want so if i reduce the dimensions - the next 'save page as file' dialog i get will be to small (the same size as what i made the 'file exists' dialog
dillo saves one dimension size for the two dialog boxes maybe 2 separate size dimensions for 'save page as file' and 'file exists' dialog
If you have a working patch I could merge it into 3.1.1. Otherwise I can queue it among the other issues, as I would need to investigate further how to solve it.
I have a patch somewhere that switches to a native file picker, which may solve one of the problems (it also remembers where you saved the last file). But this will probably be added in 3.2.0, as I'm finishing bug fixes for 3.1.1 (no more features for now).
