Hello John,
I don't seem to have a problem with all (7) of Office 2007 applications
open/running on Vista (64) but my power plan is set for Balanced and set to
'never sleep' (except in trying to duplicate your problem). It sounds like
you have another application/hardware hanging . You might want to look at
some of the settings for your power plan and tweak were appropriate.
Control Panel>Hardware and Sound>Power Options
Try this link for MS TechNet titled "Windows Vista Reliability and
Performance Features and Improvements" and focus on the Built-In
Diagnostics.

Good luck!
