New Blogger layout problem

Sometimes, when I use the Template or layout option in the new blogger, it goes into a strange type of layout page - without all the links on top.

Can't see the blog title, nor the links to posting, settings, template, view blog. Also the Dashboard, help and sign out links.

Basically, it sucks out the top of the page like into a black hole...

And - it doesn't allow you to move the widgets around !

Can't create new widgets either . It's a very bad problem and it's been causing problems.

What's strange is that the problem comes and goes without warning. The same browser, same computer. One minute it's there, next minute it's still there, next hour it's still there, but then nex next hour - it's gone !

Poof ! Just like that. I don't like that.

If anyone figures out why this bug comes - do let me know.
It comes in Internet Explorer and Firefox as well ...

At the same time. Probably something wrong at blogger.com Anyway , do tell me if anyone else hgets this problem
