Font issues?
Not that I am aware of.
I just downloaded the file and installed it to my eSword system (instead of using the build from here) to make sure I am seeing the same thing you should be seeing. I can't really see it.
My default eSword font is Georgia. The ToolTip NT editor font is set to Trebuchet MS.
Can you post a quick screen shot so I can see what it is doing?
Thanks
Roy
