According to the change log for 3.96, that should have been fixed:

"Updated the Planet window so the Build Queue buttons don't break out of their frame in Normal UI scale."

Have you tried a Steam verify files to make sure you got the whole patch?

Re-installed it, started a new game, still have the queue in the upper left corner.

How do I add a file?  nothing pops out to me.  And yes, I have several different starts/saves from different times yesterday & today. 

The usual method is to place it in a file sharing system like Dropbox and then paste a link in a reply.

I got your save and loaded it into GalCiv3 on my computer.  There was nothing wrong with the build queue.  It was where it is supposed to be.  I guess the problem isn't stored in the save.

I also see that no more black holes?  Just antimatter sitting around?

"normal UI scale"?  I have a "gel ui" (unchecked), but nothing that says specifically "normal ui scale".

Pretty sure it's a graphics incompatibility, tried windowed/no-windowed, lower res, nothing changed the position.  I guess I'll try a new video driver (hate to mess with what has been working with all my other software), but my 1080 ti hasn't had any other issues with games and on this version (436.30)(current ver is  441.42, so it's been a while)GC3 has been behaving for quite a while.

Here's something that might work.  Go into Documents\My Games\GC3Crusade and find the file Prefs.ini.  Rename it to something else, like PrefsOFF.ini.

Start a new game and see if the problems still exits.

The game reads Prefs.ini when it starts.  If one doesn't exist it will create a new one with all the default values.  Sometimes some strange values get into Prefs.ini and doing this will eliminate them and the problems they cause.

Also, the UI Size is the option just above the Gel UI option you mentioned.  Make sure it is Normal.

I will also confirm renaming/deleting the prefs.ini file puts the build queue back in its proper place.
