Are you using any map plugins?
I looked at the eq2ui_mainhud_map.xml file and there was a small change, maybe recently. The first page is:
<Page eq2opensound="ui_window_book_open" eq2usescomwndcontrols="true" Location="237,105" Name="Map" NormalSize="484,640" OnHide="StartUp=False" OnHoverIn="TM_Plugins.OnHoverInWindow.Activated=true UserResizable=false" OnHoverOut="TM_Plugins.OnHoverOutWindow.Activated=true" OnShow="TM_Plugins.OnShowWindow.Activated=true Reset.Activated=True QM_Process.Activated=true StartUp=True" ScrollExtent="484,640" Size="484,640" UserMovable="true" UserResizable="true" version="1.1.0">
and it used to be:
<Page eq2opensound="ui_window_book_open" eq2usescomwndcontrols="true" Location="237,105" Name="Map" NormalSize="484,640" OnHide="
TM_Plugins.OnHideWindow.Activated=true StartUp=False" OnHoverIn="TM_Plugins.OnHoverInWindow.Activated=true UserResizable=false" OnHoverOut="TM_Plugins.OnHoverOutWindow.Activated=true" OnShow="TM_Plugins.OnShowWindow.Activated=true Reset.Activated=True QM_Process.Activated=true StartUp=True" ScrollExtent="484,640" Size="484,640" UserMovable="true" UserResizable="true" version="1.1.0">
so it's missing the TM_Plugins.OnHideWindow.Activated=true command when you hide the map window. I don't use any map plugins myself, and the map seems to work ok.
What other UI mods do you use? Did you all just use the "Re-Download All Files" button?
