I update my Squeak4.1-9883-beta.image to Squeak4.1-9902-beta.image, without
troubles.

Drag and drop of projects still do not work.

About old compatible image versions, can't load any of my old projects for

IMHO some warning was needed in the Welcome Window of 4.0 telling people do
not do projects by now and wait to 4.1.
In the long run, we have how convert old projects for 4.1 could load them.
