Okay, I'm all up to date and I now get a failure when it tries to show the main window in CE IDE, after posting loads of noise about that iter=null issue. Still wonder if it's caused because of doing stuff with treeviews with a hidden / disabled window...but no time to look further just now.
(And Seb / markcw - wow, fltk looks usable now!)
