Filling out PDF forms in Landscape Mode

I have used Preview to fill out PDF forms in Portrait mode and it's very nice because I can save the modified file and email it to others, or just keep it for reference. Anyway, I downloaded a PDF form and tried to fill out the text. It highlights the form fields just right, with the blue glowy rectangle and everything, and when I type in the text it appears just fine, until that field loses focus, then the text goes goofy--it shows up starting at the right hand side of the field and goes in the wrong direction. It's as if Preview still thinks that the PDF is in portrait mode even though it's in landscape mode. Do you know what I'm doing wrong or if there's a fix out there?
