Problems with science and diplomatic screens

[jaw]

I have a problem with the graphics in the diplomatic and science screens in V. 1.16f.
After I play a few rounds the arrows that link civilizations/sciences together disappear. So does the icons
for improvements, units etc. in the science screen.

What can be wrong ?
can it be because I play a scenario with modified rules ?

This problem has been reported. Whether the reports have been heard is anyone's guess.

I don't think the modified rules have anything to do with it. The lines just disappear.

Personally I'd say that's not even the biggest problem with the diplomacy screen. Some whole CIVILIZATIONS are mysteriously going AWOL from my diplomacy screen. E.g., I have embassy AND spy with the English, they're right next to me on the map, I can investigate their cities, but I can't talk to the queen. Go figure. Or in a game I wipe the Babylonians out, but they respawn somewhere else, at the other end of the map. They're not in my diplomacy screen, however, so I can't even ask for peace. I stay at "war" for a few hundred years, war weariness and everything, until they finally contact me themselves.
