Negative vibes from Yahoo

[gibbousmoon]

I started getting the "negative vibes" message from Webmail-Yahoo a
few days ago.  I'm using TB 3.1.3, Webmail 1.3.9, Webmail-Yahoo 1.4.7.

The Error Console has this:  "YahooPOPBETA.js: loginHandler :
Exception : TypeError.
Error message: mainObject.m_aLoginForm[0].match(patternYahooSpanURI)
is null 399"

Has anyone else had this problem recently?  What can I do?

Thanks!
