I just tried it and it worked for me.  Is this a hit and miss issue or a constant one?

4 different 1065/1120S clients and none worked, Fed or State.  Already did a refresh updates. Went into first 1120 client and it works on 4 of 12 forms. So it's a hit or miss.

I just tried one 1120S and one 1065 and both worked.  I'll keep my fingers crossed that it will be more like a Bigfoot sighting for me rather than a regular occurrence. 

Just as a side note, I have run into the issue a couple of times now.  I have also bumped into last year's issue where you had trouble selecting a tab (like letter) without exiting the federal return to be able to access it.  Lastly, for the 100th year in a row, I still can't print electronic filing reports on one try.  Still have to click on the selection twice before the thing works.  It's nice how Intuit keeps us feeling at home by carrying over issues from year to year.

Sometimes F12 works on first time but certainly not always.  But always works on 2nd try. 

Yeah, you never have the kick the starter more than twice but it would nice if things started on the first kick.

I was having this problem with a a1065, first time ever in many years using PS.  Closed the return, reopened in Homebase and it's working now.  Keeping my fingers crossed.
