can you increase font size in any of the windows

[Meethos]

I like to read bigger fonts on computer, is there a way to increase the font size on say 'story' boxes etc?

Check some of the font extensions available in the forums. One is here: https://www.fantasygrounds.com/forums/showthread.php?25600-Using-FG-at-the-tabletop&p=227962&viewfull=1#post227962 And there are others discussed in that thread.
