My b2evolution Version: Not Entered

Hi,
I have a strange problem. I upgrade my b2evo version to 4.0.3 without major problems with the skin (even with some modifications I did). The only annoying bug is about the evobar.
On admin side, no difficulties. On blog side (on right), I'm unable to select "edit my profile" or "subscriptions". I see them, but no way to get them selected, and it doesn't have an arrow like on admin side. Curiously the menu on right side are working.
Changing skin cancel this problem, but I really doesn't to change for now.
I'm not sure it's clear, but I can give access to my blog if necessary.
Thanks
Mel
