An irritating niggle...
 

.....seems to be present at the moment on Pprune. I log in with user name and password and ask it to remember me. I read a thread and when I move to the next thread it asks me to log in again. It is becoming a serious PITA. What am I missing/ have I done wrong and how do I rectify it it. It didn't used to be like this; I could log and move from thread to thread and forum to forum with no probs. Help please.
