Yeah these disappear way too fast. Even just skimming the text I can barely get to the end of it before it's gone.

Agreed. They originally stayed on, just like the screen when you settle your first city. No idea why they changed it.

I'd prefer if there was a button we had to press to remove it. It is far too easy to accidentally click on the screen when it appears.

I can not see the picture (and the picture when founding first city). These screens showed the text, but no pictures I don't know if this is a problem with my graphic card or else, but other visual is okay.

A confirmation button is a good idea.  That way, you can't claim "I missed it!" when you actually had to search out a means to close the thing.

Issues like this make you wonder if the coders & designers ever play the game.  for example, how come there is no 'next' button to press so you can scroll through all of your active units?  And how come there's no 'center' button to center the screen on the active unit?  And there are numerous places where the text disappears way too quickly.

One of the reasons that I purchased this game is because they had the same development team that did Galactic Civilizations, which is my favorite game of all time.  There are hundreds of little programming nuances in GalCiv that are missing in FE.  If it's the same programming team, why?

Clicking their icon in the left hand assets scrolly thing should center in on the unit (IIRC). I have no problem with the strategic zoom to find units. Its pretty easy to give them their move orders from paper scroll screen too.

Also I don't think it disappears all that fast as far as reading is concerned. If anything a "Continue" and "Replay" buttons should be added. More time to look at the artworks .
