(see bug 477014 comment #4 etc) Detaching a busy tab to a new window leaves the pointer as an hourglass when over the chrome of the donor window. Reproducible: Always Steps to Reproduce: 1. Open window with two tabs 2. Load a slow page in one tab (eg http://hg.mozilla.org/mozilla-central/annotate/907dbdbd084f/browser/base/content/tabbrowser.xml ) 3. While the tab is "busy" drag to open a new window 4. Hover the chrome of the first window Actual Results: Mouse pointer shows an an hourglass Expected Results: Mouse pointer as a pointer

Not quite how I imagined it - but bug 481359 has removed the hourglass; I can't see any other manifestations of the problem at the moment so ... => Fixed by bug 481359 :-]

Yeah, looks fine. Marking as verified fixed with: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2b6pre) Gecko/20091217 Namoroka/3.6b6pre (.NET CLR 3.5.30729) Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.7pre) Gecko/20091214 Shiretoko/3.5.7pre (.NET CLR 3.5.30729)

It does occur if ui.use_activity_cursor is set true; So it will become an issue again if the default setting is changed in bug 482985.
