Hi system32AUT,
This is a bit different than the problem from the beginning of this thread, but let's see what we can figure out.
Are there any conditions configured, either on the Bitfactory Alex Dienstplan CDK Links.INI Flex config file itself, or on the Bitfactory Alex Dienstplan CDK Links predefined settings? Can you share a FlexEngine log file (at log level DEBUG) of the full session for a user who is not receiving the shortcuts?
