You must ALWAYS check for TRAN_GROUP before following transient_for. When TRAN_GROUP is found, Client.group will always be !NULL. Some smart action should be taken using all members of the group in this case. + +When using coordinates/sizes of windows, make sure you use the right area. The +Client.area rect is the reference point and size of the *CLIENT* window. This +value is not what you see in any shape or form, and gravity is applied to it to +translate it into what you see.
