Hey, I ran into this today in Chrome and I'm not sure whether it's something on my end, or something about the default chat font, but I noticed that in the bolded result of a dice roll (in this case, it was /roll 2d6), both 6's and 9's are squashed and somewhat unreadable (that is, I know what they say, but they look squashed). I don't know if you specify a font for the chat display or if Chrome is picking one, but I thought I'd raise the issue.
I've attached a screenshot to show what I mean.
Here's the computer specs:
OS: Windows 7 Enterprise, 32-bit
Screen Res: 1280x1024
Browser: Chrome 20.0.1132.47 m
Now, if nobody else has this problem, I chalk it up to poor rendering on this computer. However, if it's happening for other folks, it might be something to look into.
