1. Open two Mozilla windows 2. Click on a link to save a file (the Save As... dialog should open) 3. Switch to the other window and load a page that has a form submit button 4. Click on the submit button What I noticed: nothing happens with the form submission and the button acts very strange (stays pushed in without pressing the mouse down; hover presses it) This goes away as soon as I deal with the modal Save As... dialog, and the form submission is ok. It is strange, however, that if the Save As... dialog is indeed application modal then you shouldn't even be able to do anything with the other window.
To event handling.
the dialog is (I think) supposed to be modal for the window, not the whole app. however, having the dialog up shouldn't cause other windows to choke (and it's not only forms - clicking links also doesn't work until you close the dialog) i'm sure this must be a known issue, but i can't find it. confirming in the hopes that someone else can. (i'm using 2002091908/trunk/win2k)
I've come accross the same problem running Firefox 1.0RC1 and 1.0PR. Not only does it effect buttons and links, but you're address bar doesn't update if you change tabs, and while you can create new tabs, you can't browse around.
Looks related to bug 74331.
Also related to bug 150006, perhaps.
