LE [Help] Issue selecting cells in the Region Editor window

[AndrealphusVIII]

I want to add certain cells to a new region, but I'm having trouble doing so. Especially the window to select the cells (in the region editor) is what I can't seem to figure out.

 

Here's a screenshot in which I explain my problem: http://imgur.com/a/Alwgv

 

Could anyone help me out on this?

 

Thanks in advance

 

Kind regards

 

Andre

 

Edit: Sorry, I missed to mention the part that the game I'm talking about is Oldrim (Skyrim 32bit). My bad.
