Synopsis: Crashing

Description
I have just started my "FirstSteps" project with EiffelBuild to get a feeling for the tool and its capabilities.

I am seriously disappointed by its performance. It crashes often on me with a message of "unhandled exception" and some kind of trace back or stack dump. It seems always to be related to pick-and-drop where I seemingly target some unexpecting display item. I have not been able to recreate such interactions as the reaction takes me by surprise.

Within the Layout Constructor pane I have the impression that items sometimes are not aware of their context. Like clicking directly onto a item within a tree, just after activating it from the Widget Selector pane,  triggers an error while first clicking onto its parent makes it working fine when licked on after. Clicking to display the properties. Sorry, at the time no better description.

A really nasty bug:
Started EiffelBuild, from the File menu selected New Project, Windows Open File dialog shows located within the esbuilder.exe directory. I terminate the program thru the taskbar program (X) icon. Then I adjust the shortcut with the intention of opening the program directly in the "Eiffelbuild User Files" directory. No window appears while the taskbar icon shows the program as started. The program cannot be terminated by clicking the (X) icon in the taskbar dropdown, requires me to use the taskmanager. Several new attempts to start end all the same way. 
I end up tinkering in the Windows Registry, located the EiffelBuild section and to my astonishment see the windows top-left coordinates (x,y) defined as (-32000,-32000) !!!
Resetting those values make EiffelBuild visible again on next program start.

More to be revealed later.
