Following on from my last post, and the comments therein, the main window of Kharne is now much smaller - with dimensions of 792x725. With the optional minimap and monster view displayed, this is what it looks like on a monitor with a resolution of 1280x768:
To do this, I've had to simplify the main window considerably and change the information that is always visible. I think I prefer the newer look - its more streamlined and less distracting.
Eventually I hope to get the main window down to less than 800x600 so it can be run on this lower resolution in extremis.
