Exceeded font space error message
 

Hey all,

I'm in the process of making a workbook with two different sheets with about 40 or so graphs each. However, I get a weird message saying that I have exceeded the font space and new font changes can't be made.

That was easily enough fixed by splitting those two sheets into two different workbooks and that just works fine. But I am just curious as to what exactly is the font space limit. How many fonts can you have?
