title="RESOLVED WORKSFORME - Calc - Errors in function "Conditional Formatting" in Calc, some formatting to save or modify the file ...."
href="show_bug.cgi?id=60118">bug 60118</a>, re-attached for convenience as the original

don't see much of the grey background on the right.
Bibisected with win32-6.3 to
