WP Admin – Connectivity Issue? Please HELP!

I installed wordpress with one-click installation on 1st January using simplescripts/bluehost. My site is: http://www.projectlivewell.com

Having used it for 2 weeks I have a serious issue:

I can log in to the dashboard with no problem but once I try to perform actions like edit/add post, play around with widgets etc the screen just ‘hangs’ as if there is something wrong with my internet connection…

Except, there isn’t anything wrong with my internet connection – I can access all other web sites no problem.

I am exchanging emails with Bluehost who say this is basically an unheard of problem and is not being reported by anyone else on my server.

As it stands, over the past 2 weeks it has worked sporadically – perhaps working normally one day out of 5. I’m pretty much close to giving up blogging with wordpress!!

Does anyone have ANY idea what the problem could be? Really, any suggestion would be helpful.
