There is the first bugs:
General bug, in the Image editor, the Fill tool sometimes will totaly crash the program! Can easy reproduced: open new, empty black image, and fill with black. The program exiting...
Bug in the Enterprise palette selections in the 16 colors mode: now you can select any colors for 8-15. This is not good. On Enterprise you can select the colors 8-15 with the FIXBIAS register. In the Nick chip this is a 5 bit value, and select the top 5 bits of the colors 8-15. For example the FIXBIAS is a 0 then the col8-15 is a 0-7. FIXBIAS=1 then col8-15=8-15, FIXBIAS=2 then col8-15=16-23,etc
