I'm not sure whether I'm doing anything wrong or whether my laptop's being a craptop or if it's my internet connection messing about, but intermittently (sp) I can't access my private messages? just comes up with a white screen?

Like today, I replied to a PM that a member sent me, came out of private messages, looked in a couple of threads, tried to go back in just to see if it was behaving and it decided to white screen itself again and I had to use the back button to get back onto a page, I haven't tried again yet.

What's going on? What's with the PM hokey cokey? I'm confused and worried cause idk if I'm doing something wrong or if it's tech things going wrong?
