Dreamweaver CS4 unexpectedly quits

Question

HI,
Dreamweaver CS4
iMac 10.6.8
4 GB RAM
Recently Dreamweaver crashes all the time - in a working day could happen up to 9-12 times.
I already did a “clean install” for CS4 twice and I clean the cache files, delete the preferences and it still unexpectedly quits = losing all the work and I have to start over.
Most of the time Dreamweaver does not remember on what site I was working on, nor the workspace (or the encoding set).
Using Activity Monitor (the small pie on the dock), I noticed that the application is gradually using more and more of my RAM - until it's out of RAM, more than 2GB, and then crashes... Dreamweaver is a text editor application, that supposedly doesn't need a lot of RAM...
Please advice:  why is it doing this, and how so I stop it, so I can work normally again? 
Thank you,

I know absolutely nothing about Appale MAcs but in a windows system if this happens then it is a clear sign that the Application in question has been corrupted either by some viruses or some other form of malwares.  The only way to resolve this is first to scan the system with a good Anti-Virus product like Microsoft Security Essentials (free from M$).  Second you need to reinstall the product but before you can do this, you need to remove all the registry entries so that the product can be re-installed on the same system.  This is a tricky area and because it does not apply to you, I won't bother you with the details.  You also need to de-activate the product so that Adobe can re-activate for you after the re-install process otherwise Adobe servers might think you are trying to cheat them by re-installing on another system without any authority.
Now all this is completely useless to you because you don't use Windows system.  Perhaps somebody can post details about Apple Macs.  Wales lost in Rugby to France and ManU are no longer leading the premiership in the UK.
Good luck.
