Thank you for responding:
when I boot TC on an older machine the display stays black.
I can right click and see the menu, but I have no background
nor a logo - just nothing.
On another PC I have the colored (bluish) background, logo and mini menue.
So I found out in the meantime, that it has something to do with that individual
machine. May be TC does not recocnize the Nokia LCD monitor?
I will play around a little bit more and will post my results.
Have a good day - I thank you for giving me some of your time
