Thank you for providing the disk image. I like the continous scrolling 
so I will check reduced verion in more detail later. However, why is 
text scrolling implemente with left mouse button? I would expect to use 
middle button as in the original system. Also using the scroll wheel 
would be nice.

An other question:
My port to Linux discovered bugs like below excerpt from Kernel.Mark:


SYSTEM.GET(pvadr, p); SYSTEM.GET(p-4, offadr);
       IF (p >= heapOrg) & (offadr = 0) THEN q := p;   (*mark elements 
in data structure with root p*)

Memory at p-4 is accessed before p is tested for zero. This of course 
traps at non RISC-5 systems. Also unclipped UpDown arrow and closing 
Stars viewer trap the system. Is there a chance to get these bugs 
corrected in original and/or your system?
