RE: GtkComobBox with appears-as-list - broken? going away?

["Ian Puleston" <ian underpressuredivers com>]

Thanks. I found this bug report opened a couple of years ago which seems to be the same thing that I'm seeing 
with appears-as-list set:

https://bugzilla.gnome.org/show_bug.cgi?id=743683

If I can reproduce this in a Linux version as well as in the Windows version then I might look into possibly 
fixing it if I get some time.

Those mock-ups for the new replacement look great. And with a proper scroll bar - that will keep us 
detractors happy :-)
