It is 1.26e which uses 640x480 screens, so that is why they are small. My monitor is 1920x1080 so for the windower I set the resolution in the "eaw.ini" to 1680x1050 which leaves room for the border on the screen with a little more space at the sides. It sounds as though you have the same as me

The next thing to try will be 1.28E. This uses 1024x768 selection screens.
I'm running in Win 10 at the moment so I will switch to Win 7 and organise a 1.28e download for you.
