"GFX Combobox doesn't work on GTK" This is a GTK specific bug (possibly Mac too). When a combobox is dropped down, then clicked on, the click event is not sent to the frame. Thus, the selection isn't updated, and onchange events aren't sent out. This seems rooted in the code here, so I'm giving it to Pavlov even though it may really be somebody else's: widget/src/gtk/nsWidget::OnButtonPresSignal() ... if (rollupWidget != thisWidget... ... In this case, even when I click on the rollup widget, 'thisWidget' and 'rollupWidget' have different values, and the Rollup handler is called. In a random fit of desperation, I remembered Pav saying something about removing the CaptureMouse() call on Friday, so I unleashed nedit on layout/html/forms/src/nsListControlFrame::CaptureMouseEvents() and axed the code Rods marked "// XXX this is temp code" which calls the widget's CaptureMouse(). It does allow clicks on other places within the app to roll up the combo. However, as with most desperate acts, it did not have the intended effect. The click was still not making it past Pav's impenetrable "if rollup != this". Can you fix this?

If there's an easy way to verify this, please let me know so that I may do so...

The duplicate bug has a better description of the problem. On Linux, go to any page with a combobox. Click on it to select an option. If the text area of the option appears to have been updated normally that the bug was fixed. Before this bug was fixed, clicking on the combobox didn't update the text or selected options, so comboboxes were very broken. Thanks!

Somebody please slap me for not looking at the duplicate first. :) Using the 1999110908 build and the handy test case at the URL above (thanks very much), this is verified fixed under Red Hat Linux 6. Marking as such.
