Now I managed to make EasyDocking work again on Win7 with the Lazarus 
trunk, and also in the IDE :-)

Unfortunately I only could produce an big patch, covering all updates to 
the examples/dockmanager, LCL and IDE. I attached it for all curious 
users, and hope that it will not be removed by list restrictions.


The patch addresses (amongst others):

+ Full screen extent (including negative origin) in TScreen.Bounds, 
Options:Windows and in the IDEDockManager.

+ Better IDEDockManager integration, some methods added, general 
ShowAllForms etc. procedures check for the presence of an 
IDEDockManager. This could be further extended, so that the IDE does not 
have to care at all about an DockManager.

+ Fixed some DragManager flaws, in detail CaptureChanged and DockForm.

+ Improved TControl.Floating, using a new TFloatHost base class for all 
floating sites.

+ Seems to work with AnchorDocking as well.

Enjoy :-)
