Any chance you're using the page numbering control template in your report?
It will do this since it wasn't originally "wrapped" to protect against
empty reports. As far as I know it's the only standard template that
can/will cause this behavior.
If you -are- using the ReportPageNumber control template open the
abreport.tpw and search for "reportpagenumber". When you find it you need to
add a couple of lines...
Move down to the #AT containing 'OpenReport' and you'll find...
%Report$%Ctrl{PROP:PageNo}=True
Change this to...
IF ~ReturnValue
%Report$%Ctrl{PROP:PageNo}=True
END
Recompile and the problem should disappear.
