Sure... here the file http://moiscript.weebly.com/uploads/3/9/3/8/3938813/nodeeditor.zip
I am on PC Latop + Monitor

<< Does your file menu also appear some distance above the File button too?

Yes as shown on my previous image when there is a reduction!
In normal time all is "pasted" and with same size! :)
For elimate that i close the Nodeeditor and recall it...not a big deal ...just curious...

I suspect a not clean exit of some nodes! :)

Edit : in fact that is the use of the monitor! So resolved!
As soon as i move the NodeEditor on it there is reduction of the File windows when i call it!
As soon as i move the NodeEditor on the Latop there is no reduction of the File Windows when i call it! :)

Of course that is not the case with other programs ...not a big trouble! :)
If I use Moi on the Monitor there is no reduction! (without call NodeEditor)

but a little trouble...when I call it...in some case...
Moi on the Monitor full screen...Node Editor on the Latop ...I can't see the File Windows...I must reduce the Full screen of Moi !
If the Node Editor is on the Monitor over the Full screen Moi all is fine! :)
Again not a big deal :)
