Migration script

It seems the migration script is being ran every single time I log on now. As a result, I see nothing on the screen for a long period of time. After a while a dialog pops up, which indicates there is an issue with some desktop link files in my profile. Could somehow the migration process be announced/displayed/indicated so that it is clear what is going on? Why could the script have problems with updating desktop links inside my profile? The diagnostic information seems limited. Thanks, Julius
