Yahoo Mail issues

I have been having trouble moving my emails to the corresponding folders for about a month now.  It will allow me to move the first email without a problem, but then it won't allow me to move another without closing the program and resigning in.  Is this a settings issue?  Was there an update that made this an issue?  I have been using this email for years and just started having this problem. Any help would make my life much easier. Thank you.
