Page Orientation Problem

[T]

I have this report that is setup to preview and print in the landscape
orientation.
Now and again I get this problem where in preview mode it shows up in
potrait orientation.
I don't understand why.
please help.

That could happen if you moved the database to a different computer that has
a different kind of printer, or if you replaced the printer driver.

If neither of those apply, it could be this bug:
