This is probably covered somewhere but I can't work out a search expression that locates it.

I have several computers and need to manage my task list as I move between them. How do I get RTM to force an update to the server so that they are synchronised.

At the moment I am having to log out of RTM on one computer and then back in on another. Is this the only way to do it?

Gmail somehow manages to keep keep uptodate on all computers, but it appears that RTM doesn't?

Thanks for any advice
