Perhaps ,you must reprogramm it for the new systems, OS4, MorphOS or AROS.
 It was programmed in AmosPro, so I don't think I can write it for other Os'es than 
OS 2.0 -> 3.9. For example; AmosPro can't handle high screen modes very well. 
SysLock is only for "real" classic systems. 
If there's a need for such a program on other platforms then maybe someone else 
(with the right skills) is willing to program it in a different code language.
