Add a background color, and the button doesn't appear. Reproducible: Always Steps to Reproduce: 1. Create a popupbug.xul file with the following content: <?xml version="1.0"?> <window xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" style="background-color:#fff"> <label value="Some Random Content" /> </window> 2. Open it from with XULRunner using a command like the following: var w = open('popupbug.xul', '_blank', 'chrome,dialog=yes,titlebar=no,popup=yes'); 3. Notice that no button for the window appears in the taskbar 4. Now delete the 'style="background-color:#fff"' attribute in the <window> element 5. Open the window again, as before. 6. Notice that this time a window button appears in the taskbar :-P Actual Results: Window taskbar button appears when it shouldn't Expected Results: The presence (or lack thereof) of a button in the taskbar should not depend on the background color of the window. Note: A workaround for this problem is to give the window a background color in the style attribute (or corresponding CSS file), and then programatically set window.document.documentElement.style.backgroundColor = 'transparent'. Oh, and this is running XULRunner 22.214.171.124, on WinXP (no service pack)
I'm unable to reproduce this bug in Firefox 2.0.
