I am getting an error in VFP9 report previewer just as the previewer is opening for the second time:

Table has no index order set
Line 0 in openresource()
frxpreviewform.Error()

I have spent hours trying different workarounds. I have it tracked down to restoring a view. If I restore the view this error is guarenteed. Here are my exact steps:

Open modal form, open data environment etc
In INIT() method save the current view
Run a report
Previewer works fine
Restore the view (because the reports do lots of damage)
Run the reports again
Immediate error as the previewer is opening.

Does anyone have any ideas?
