When I log on again all loads normally.
This usually doesn't happen if I have to reboot.
I have seen a lot of postings with a similar problem where people can't get past the logon screen and lots of radical solutions involving editing the registry, reinstalling windows etc.
At the moment this is just an annoying glitch but I would hate it to turn into a serious issue.
I've seen the serious version linked with spyware removal - I run Spywaredoctor about once a week. Nothing dramatic found recently
Any suggestions as to how to identify what is happening
Thanks
