Dreamweaver & Server freezing/ hanging randomly. Help!

Upon changing any code on a CFML page and saving it, then reloading the page in the browser, the browser hangs. It just spins and says "waiting for (testing server)".It will spin for many minutes. There is nothing happening in Firebug. There is nothing locking up memory or CPU inside the testing server. Interestingly, even other pages on the same site can be accessed and served out fine through the browser. This problem of freezing up seems to have something to do with Dreamweaver sharing a file with the browser at the same time.

While the browser is frozen you also cannot click on anything in Dreamweaver. "Not responding".

And the only way to escape the freeze is to restart the coldfusion service on the server. What is going on here? Why does this keep happening?

I am running Dreamweaver CS4 on a  Windows XP Professional machine. We connect to a Windows 2008 testing server that uses Coldfusion 8. This is very frustrating because there is seemingly no error in any logs anywhere, only freeze up.

It doesn't matter if the code I write is javascript, html, cfml..doesn't have anything to do with whether the code is in error or not. It validates, it is a simple change of a variable name, and when I load it at random times  it will just freeze up. Was happening a ton this morning then went all afternoon fine now it's happening again.

Please help. Thx
