Has anyone else experienced problems with the session cookies? Is there any way to disable their use?

I lost 3 hours worth of track clean-up work to the session cookie - Sync in car to laptop, go off edit, come back and BLAMO, no sync allowed due to session cookie mismatch.

Has anyone else experienced this problem or am I the only one with a player install that doesn't allow for great freedom in removing the player from the car and therefore am the only one using this sync method?
