I can confirm that Outlook Express and Thunderbird on windows seem 
largely unaffected even using *both* at the same time.  I have been 
alternating back and forwards with no ill effects other than some folder 
subscription winges.  You appear to need to close down and re-open each 
program sometimes to make it switch over
