Localhost problems

I'm using AcquiaDrupal on my desktop for trying things out. Love how fast it builds up apache, mysql, php and drupal AND drupal modules. Love how easy it is to start / stop, add multisites etc. HOWEVER - it keeps dying on me - cannot start services. Works for a while, then ... nothing. Perhaps I have another service interfering. No skype, what could it be?

I wiped it out, re-downloaded acquia (new version as of yesterday!), and every thing's fine. Have to keep an eye on this.
