Hello everybody!

I have a problem with my document libraries in my team site. I know when a user open a file from library (so it checked in), after user close the file, it must check out automatically. Sometimes after closing the file it takes some minutes to checking out, so it bother other users because they at the moment no one can edit the file.
In my last exprince it took almost an hour until user could open file again to edit after closing!!! It becomes a big problem in my site. Until we find a solution, is there any way that I close the file by myself??? Thanks a lot for your time!

Please help me, thanks for your time!
