Rev performance: help!

[Jon Seymour]

Hi all,

I'm flipping out today over what seems to be a sudden and  
inexplicable degradation in Rev's performance. When I started up the  
stack today, everything had slowed to a crawl. Eventually, I tried  
opening an older version of the stack on my laptop (a separate  
computer) and...same thing! After hours of this I even tried  
reinstalling Rev, and still the same behavior.

Any ideas, folks? Boy, I'm hoping there's a simple answer!

Thanks,

Jon
