[CE U1] Cell Library and Properties Window

Hi,

usually I have my Properties Window docked right side of monitor thus open all the time.

I open Cell Library Dialog, select cell lib:
C:\Programme\Bentley\MicroStation CONNECT Edition\MicroStation\Default\Cell\areapat.cel

When I then click on a cell Microstation hangs.
It seems that it is taking VERY long for loading properties to show in the Proprties Window.
When I close the Properites Window i can click on cells and everythings fine.

Regards
Stephan
