Render window freezes

[thousande]

Hi

 

Somehow my render window has started freezing when I do the following

 

1. Right click an object in the object window

2. Choose Preview

3. Drag an object to the render window

 

It does not matter if it is the previewed object or not that is being dragged to the render window and it does not matter if I close the preview window before #3

 

I have to shut boot CK and everything works until I open the object/preview window again.

 

Not sure if it is related but I get the following in EditorWarning.txt when I close CK:

 

Form '' (010013AF) of type NAVI in file 'MyMod.esp' was not freed.

 

Anyone else experience this?
