FM8 compatibility with Windows 7

[Fred Ridder]

Gang,
 
Does anyone have solid information on whether or not FrameMaker 8.x is compatible with Windows 7? 
One of the engineers in a group I work with just got a shiny new laptop with Windows 7 (so far our corporate IT people are only allowing Windows 7 on brand-new machines), and the IT folks insisted that she has to install FrameMaker 9 rather than FrameMaker 8 because FM8 is not compatible. Of course, this now causes file compatibility issues since everybody else in the group still has FrameMaker 8 and can't get FM9 yet because the IT group's "purchase software" website only offers FM8. Yes, I know she can do a Save As to save files she works on in FM8 file format, but she tells me that FrameMaker requires her to change the filename when she does so, and that causes issues with our version control system. I'd love to have some solid information I can forward to the IT group to convince them that it really is OK to install FrameMaker 8 on a Windows 7 machine. (Or I'd like to know that it is definitively *not* OK so that I can work with this engineer to come up with a practical and foolproof workaround.)
I tried searching for compatibility information on Adobe's website, and the closest I could come were a couple of pages that told me that FM9 is "now compatible" with Windows 7. Useless. And I tried searching Microsoft's website, but the compatibility spreadsheet they provide for "IT pros" doesn't list *any* version of FrameMaker among the 10543 entries, and their Windows 7 Compatibility Center only lists FrameMaker 9, and only with the indication "no information available". Even more useless.
