 Qgis is crashing/freezing after opening more attribute tables than
 comfortably fits in computer screen.

 How to replicate:
 1. Configure Your QGIS to "Open attribute table in dock window"

 2. Open any shapefile containing some attribute data

 3. Press "Layer -> Open Attribute Table" few times until you will have
 more attribute tables than comfortably fits to your screen. Qgis will
 freeze.

 Some more realistic example:
 1. Imagine, You have small screen computer and two layers with attribute
 data containing 10 columns.

 2. You want to display attribute tables of both of them one beside other.

 3. Open first one.

 4. Open second one. QGIS will freeze, because second table will not fit to
 your screen.

 Software details:
 OS Debian Lenny KDE 3, Debian Squeeze Gnome
 QGIS: Latest Trunk

 GDB output and 'bt' attached
