Need help with full screen being too big..

Just coming back to the The Realm (which is fantastic and just what I need at this point in my gaming journey where nothing new seems to keep my interest.) I'm having an issue that when I make the game full screen it is actually a bit too large and I can't see the chat bar. Is there a way to fix this or do I need to adjust my PC resolution settings in general? Thanks!

I fixed it and figured I'd post in case anyone else had this problem. If you right click on the desktop icon, go to properties, then select the capability tab you can put a check mark in "640x480" resolution tab. Solved all my problems. Happy Gaming!
