This solution to this is actually very simple. Go to your EQ folder. Find the file eqclient.ini and open it in a text editor (i use notepad, its the simplest to use)
hit ctrl+f, type windowedwidth, you should see something like this:
WindowedWidth=1280
WindowedHeight=768
Width=1280
Height=768
FullscreenBitsPerPixel=32
FullscreenRefreshRate=0
WidthWindowed=1280
HeightWindowed=768
change it to this:
WindowedWidth=800
WindowedHeight=600
Width=800
Height=600
FullscreenBitsPerPixel=32
FullscreenRefreshRate=0
WidthWindowed=800
HeightWindowed=600
I'm using 800 x 600 here, but you may need to fiddle with that a bit. If 800 x 600 isnt working, try using your monitors native resolution instead. Eventually, you will get a combination that works, just keep trying.
