“lost network connection” when posting new post

Hi,

about 60% of the time, i am having problems with posting new messagesin WordPress 2.0.1. Saving works fine, yet it is always a gamble whether the post gets through or i receive the following error message in Safari:

Safari can’t open the page.
The error was: “lost network connection?? (NSURLErrorDomain:-1005) Please choose Report Bug to Apple from the Safari menu, note the error number, and describe what you did before you saw this message.

Any idea on how to solve this problem?

Thanks in advance.
