>Colin, thank you for your detailed comments. They shed good light on the nature of the problems. With your advice in another message (Re: VFP 9.0, SP2 now available Thread #1260474 Message #1260835) also in mind, I now see two options.

>Option 1: Uninstall VFP, then reinstall VFP and apply the SP2 Refresh1. Then test which reported bugs are gone and which aren't. Then decide further. This scenario can best be done on a test machine.

Then check whether it indeed contains the fix to ReportPreview.App. If not, a restore of the older Report*.App files is required and a reread of your article on how to build my own ReportPreviewer and start coding it might be a viable option. This can all be done on the development machines.

What about option 3?

Install VFP, Install SP2, Make a copy of the all the Report Apps from SP2, Uninstall VFP (there is no option to uninstall sp2)
Reinstall VFP9, install SP1 then overwrite the Report files with those from SP2.

Now thw toolbar works and you have the benefits of the advanced classes and apps of Sp2.
