Just reinstalled AACW with patch 1.16 Release Candidate 10a.
Minor problem: none of my F-keys work. Hitting any of them causes only a brief flash of whatever F-key-related screen should present itself.
I say this is "minor" because I have discovered the workaround: I hit Esc to go to the main menu, then hit Resume Game to get back to the map, and now all the F-keys work as long as I do not click on any map units. If I do start clicking and moving forces around the map, the F-keys go nonfunctional again, and I have to repeat the above workaround.
Could be just a corrupt install. I never had this problem with any previous patches.
