Font info disappears from x-ref format

[Klaus Daube]

Dear all,

In the FM documents (FM-9) of a customer a special symbol inside an x-ref format loses its font 
information - only from time to time, but quite frequently. The symbol is then displayed as 2 
rather than the page-symbol. Refreshing the screen with CTRL+l does not help. The only bypass is 
to save the document, close it and open it again. It happens on XP as well as on W7.

The x-ref format:
<X:CrossRef><$paranum>,\ <U:SpecialSymbols><U:Black>2<Default ¶ Font><X:CrossRef>\ <$chapnum>-
<$pagenum><Default ¶ Font>

The character formats are:
X:CrossRef         Color blue, Pair Kern
U:SpecialSymbols   Wingdings, 9.0pt, others: as-is
U:Black            Color black, Pair Kern

Could the reason be in the accumulation of character formats?
