Details:

Hi, 

not really sure, whether this is a problem in the app, or maybe a levelling
problem in -gui or my backend. However, I saw this problem in DBModeler here
first:

* start dbmodeler
* open a postgres DB model from a database 
  * the database should contain many tables, so that the diagram view is not
large enough to show the tables without the need of overlapping.
* switch to the diagram view
* try to grab a table on the headline
   * below the mouse arrow, when clicking on the headline of a table to be
dragged, there should be at least one another table a level below
* after try dragging the window, and then releasing the mouse button, the
window stays in its original location, and the field from the table below
becomes marked and visible on top of the overlaying other table. See
screenshot.

In the screenshot I clicked on the appointment_resource table and tried to
drag it around. The "department" showed up, as soon as I released the mouse
button.

Also dragging becomes very slow, and the diagram view nearly unusable, when
there are more than a handful of tables in the model, e.g. I loaded the
opengroupware database model, with about 60 tables, the diagram view is nearly
unusable.
