[xmonad] Window gets pulled into another workspace

Hi, When I open a window on a workspace (A) and that is delayed (firefox download window is a good example since it waits for server response), and I move to another workspace (B) in the interim, the window of the latter gets pulled into the first workspace (A). Is this behavior defined and/or a bug? How to avoid this? Regards, -- Raghavendra Prabhu GPG Id : 0xD72BE977 Fingerprint: B93F EBCB 8E05 7039 CD3C A4B8 A616 DCA1 D72B E977 www: wnohang.net
