Problems with cardlayout (loadingmasks)
Backend User Interface
* tested card layout intensively [FF current stable, no plugins (fresh install)]--> really needs some work --> if connection to server is not stable (thin line), this leads to massive problems (list for Kay: got 2 different loading masks, finish loading not correctly detected, changing modules/page without waiting for load sometimes got weird experiences, especially I saw loaded stuff through the mask, but it didnt went away - seems that the events of "finally loaded" are not handled anymore if loading lasts a minute :P) --> if clicking too fast, the backend is stucked (this also happens on switching from modules wiht pagetree to modules without), stuck means loading masks reside, too. Or module/page combination (marked active) does not match the module in the content area
