It think the problem arises from the Bi weeekly option, which seems to be triggered depending on the users time of installation.
That is why a daily ( morning ) check would be nice when fairly large groups are working together using TypeMock.
Another solution could be for typemock to check the referenced TypeMock.dll version, and check for an update if the referenced version ( in the solution ) is newer. It should be doable since TypeMock is loaded as an addin, and therefore can inspect the Solution properties incl. references.
