Basecamp sees unit version older than on device

Device: Oregon 600T
BaseCamp: version 4.4.6 and earlier

A very irritating issue is that BaseCamp every time it starts up and connects to my unit, gives the message that I should install a new software version on the device.
BaseCamp sees that the unit has version 4.40 and it advices to in stall the "newer" version 4.10.
Even after just following up the install advice, it sticks to this 4.10, while it installs (of course) 4.40 (again).
It doesn't matter which BaseCamp version you use, even earlier version show the same problem.

How do I get rid of this?!!
