Updates: Status: Invalid Comment #2 on issue 245 by byorgey: I can make windows vanish. http://code.google.com/p/xmonad/issues/detail?id=245 I'm pretty sure this is caused by switching to a workspace other than the ones the windows were on, caused by conflating workspace tags and ScreenIds. ScreenIds are not particularly reliable; the attached code assumes that workspace "0" is on screen 0 and so on, which is not necessarily true. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
