Fixed bug: The formatting of column titles in Prism 6 can change (rarely).
This is a subtle bug in Prism 6.00 that we fixed in 6.01. It affects Prism Windows only, not Mac.
To understand the bug, you have to know how Prism stores column and row titles. Prism stores first the plain text of the title. Then it stores the formatting. It remembers, say, that 5 sequential characters are plain, then one is superscripted, then 8 are plain, then three are bold...
It turns out that exactly ten characters are formatted the same way, Prism 6 gets confused. Nine or eleven or any other value is fine. Ten is the problem. (Why 10? Because 10 is the ASCII code for new line and Prism now allows two line row and column titles.) So the work around is to add a character or word (or take one away) -- anything to avoid a sequence of precisely 10 characters formatted identically.
