I failed to reproduce the problem. Could you tell me more precisely what to do (perhaps even make a short video)? Are you certain the problem occurs in the master branch?

Yes, definitely occurs in master branch. I hit it all the time.

Not sure how to describe it more precisely (and don't know how to make a video, sadly).

Just realised the more info link is wrong - apologies, it should be http://forums.wz2100.net/viewtopic.php?f=6&t=13753

The other guy who reports the same issue has slightly more convoluted instructions:

"To trigger this open the research window then close the side bar but not the bottom bar so the screen looks like this.

(Image above)

Then try to select a group of units the first time it should select the group of units as expected but if you then try to select a different group or reselect the same group of units it won’t let you and you will be unable to select any units until you close the research window fully. This doesn't seem to happen on every level and sometimes it does this with the unit build screen open in the same configuration as in the screen shot of the research window."

I'm not sure if that's correct, but it is true it doesn't happen consistently 100% of the time - just frequently. I have a suspicion you may have to get to the point where the research window is arranged as above by selecting a new technology to research (which has the effect of closing the 2nd window on the left). I'm not certain of this though. If you play for a while the the research window open as shown above, you're bound to hit it eventually however.

This bug is likely a duplicate of #4229.

-Philosopher- commented

Yes. I think so.

I also looked into it further myself. It can reliably be reproduced by:

• Select a unit and/or numbered group. Then press F2. The numbered group will be deselected (presumably it shouldn't be)
• Press F2 to open the research window. Choose a technology to research (the choices on the left will close, but the window centre-bottom showing the research facilities activity will stay open). Attempt to select anything. It will instantly deselect.

This is consistent with:
"hit F2 to get the research screen
research the wall
press 2 for group 2
the highlight blinks on then off, group is left unselected"
from #4229
