Anyone else been having problems with the PM system lately?

I PM'd a lady yesterday to try to arrange a meeting today and didn't get a response.

I texted her today, again to see if she was available, and again no response.

Now my messages are always polite (I have seen the lady before but I'm always respectful anyway) so was wondering why she didn't respond, any number of reasons I know, so I wasn't going to push it, I could always see her next time she was around.

Anyway, I logged on today and checked just in case there was a message that I hadn't received a notification for, I click in my Sent Items folder and I see my original message was sent out numerous times over the space of little more than an hour, so if she's on the other end of the messages she may have thought I'm acting a bit odd and decide not to respond.

Has this glitch happened to anyone else I wonder?

(Obviously if the lady in question happens to read this she'll hopefully realise I'm not a nutter, I could try to message her again but if it happens again it'd only make things worse :/ )
