I have tested with the RTF control to see what happen and
nothing bad happen.
What I did is the following:
I create a new form and put a RTF control on it, and a command button with this code:

cFile = "c:\test\testfile.rtf"
Thisform.olecontrol1.Savefile(cFile,0)
Create cursor rtftemp(ortf g)
append blank
append general ortf from cFile
Report form rtftest preview noconsole

*******
This seems to work well
at the rtftest report I set an olecontrol and set the properties to Clip the image, and pointing to the rtftemp.ortf field
and all works Ok.
Just have to make the control taller to fit the entire page, making the detail band taller.

Hope this help
