Especially if you have a virus checker that is interfering with the 
repository and Berkeley DB. As said in an earlier post, if that is the case, 
by all means figure out the way to exclude the __repository__ directory used 
by Chandler. For reference, by default, that directory is in your profile 
directory. That directory's location is described here [1].

Otherwise, it's surprising to read this. Are there any other differences 
such as amount of RAM, HD speed, CPU that could account for what you're 
reporting, Jeffrey ? Could it be disk fragmentation, which on Windows can 
get rather bad after a while ?
