Editor Window Will Not Maximize

[Metal Kozak]

The window for the editors, (such as: Level Edit, Model editor) will not maximize to a full screen. The editors themselves work fine it is just when it's on screen I cannot maximize or change the size of the window. I can't rotate the view in the editor either. The maximize window icon (little square) in the top right corner seems to be faded out, compared to the minimize (little minus - ) and the close buttons (little x).

I'm sorry if this is a noob mistake, but I would really appreciate someone's help. This editor actually seems simple enough to use, compared to the other ones out there which require vast knowledge of script. Too bad things seem to be half working when I get them.
