thank you for this hint! :) My first posting was made at a time as I thought only one script has this issue. For this one script I had matched another line inside of register(). But all scripts of MakeHuman are affected...so... :) Anyway...your solution works as a charme and therefor the scripts are registered with blender again :) Have a nice weekend! Best regards, mcc
