Larian helped me with troubleshooting. Left clicking on screen was not working. I pressed default key assignment and it fixed it. I had never been in that screen so I do not know how it had gotten changed. I can finally play!
This may sound like an odd thing to say from someone who hasn't experienced this problem, but I'd like to thank you for posting the fix.
Too often on game forums, people post issues, then post "fixed it" with no further explanation. Drives me insane. Er. Insaner. So thank you.
