- Maybe you are using different colors than I do. Maybe you are using a
- different monitor than I do (some reduce flickering because they emit the
- light a bit longer than others - don't know the term in English :-). Maybe
- you are just not as sensitive as I am (in that regard at least :-).

- In the meantime I found out how to switch to NTSC. Yet, it was tricky, and
- still I guess there is something wrong in the WB2.0 software. It seems to
- me it checks for the ECS Denise, though it's not really needed for
- PAL/NTSC. I am now using a hack called SetDefaultMonitor (there are many
- others, too) which makes all programs think they're running on a real NTSC
- Amiga and thus makes them open a NTSC screen. :-) As far as I could see
- from the docs, it emulates the motherboard jumper.

- See above. Colors, monitors, and last not least users differ enormously!
