The XMaps Remote Control interface is loosely based on the XMaps web site, which was designed and produced by t6 Design and Media.
The content was produced with a screen resolution of 1024x768 in mind, and tested under IE6 using a range of text sizes. Since the presentation of the web pages can vary greatly between browsers, I've added a 'fixed text size' option for XMaps Remote Control, in the XMaps Options menu under XMaps Setup. When you use that option, XMaps Remote Control will display in the text size you choose regardless of your browser settings. Personally, I use an 8-point fixed text size in a 1024x768 resolution.
If you have any difficulty with the interface or its scaling, please drop me a line and I'll see what can be done about it.
