--- Comment #6 from Anthony Jagers noonetinone@gmail.com --- How can you declare something abandoned when I just commented on it? It's my bug report. To me it's non-issue.
The "Completing Installation 1%" box is normal steam behavior. I see it all of the time for other applications that have trouble starting. When I fix what the problem with offending game is, the box goes away the next time I try to start it. What I'm saying is I'm used to it.
