Dissatisfied lj user rant

I am getting tired of this. I have tried to post to other peoples' posts and been told there is an error and of course my post is lost.
I couldn't even get into lj at all the other day.
If I have posted and try to return to my last friends page, I'm backed out past the one I wanted to be at. If you back button then it should only take you back one page..not two or more.
Just now I've tried to read an entry referred by another poster and it locked up my computer. This is showing up only here on livejournal.
I am not a happy lj user at the moment.
