Dreamweaver CS4 for Mac crashes and freezes

Question

I couldn't find other postings related to this, but if I
missed something, please let me know! I've been working with CS4
for about two weeks and have intermittent success.
After I first installed, I noticed a problem within
Dreamweaver where I could work within the application, but coudln't
switch to other open apps. As soon as I tried, my computer would
freeze, forcing me to do a hard reboot. Because I was working on a
deadline, I stopped using CS4 and went back to CS3 for a few days.
I then went back to CS4 to see if I could figure out what was
wrong, and wasn't able to replicate the problem. It worked great
for a little over a week.
No for the past few days, I'm experiencing the same problem.
It doesn't happen right away and I can usually open a few pages and
work with them before I notice the problem . . . but after working
for a short amount of time, if I try to switch to another
application or use any of the items on the main tool bar (File,
Edit, etc), my computer stops responding. I can usually get a few
quick commands in, like saving the file by doing a ctl-S, before it
freezes completely, and then am left having to do a hard reboot.
And every once in a while, the application will complete
crash when I try to open a file. it doesn't seem to matter which
one, it's pretty random. I prefer it when it crashes so I don't
have to reboot my computer.
Adobe does have a knowledge base article at
http://kb.adobe.com/selfservice/viewContent.do?externalId=kb405911,
but so far nothing I have done has helped. I've gotten through item
18 on the list, with the exception of 14 and 15, and I wasn't
really sure what I was looking for with 16 (review the Console
logs).
Before I do anything more drastic, I thought I'd post
something to see if anyone else has thoughts on what to check. In
all actuality, instead of taking this any further, I will likely
just go back to CS3 until I hear more about updates or fixes.
Thanks!

Well, this is my third attempt at fixing this problem. Each
time, the application works flawlessly for a few days and then
gradually starts to freeze and crash intermittently until it
finally completely freezes each and every time I try to open a
file.
Here is a recap of what I've tried:
- Troubleshooting tasks (1) - (19), (22), (23), and (28) from
http://kb.adobe.com/selfservice/viewContent.do?externalId=kb405911.
- Reducing the display resolution seemed to work for about
two weeks, but then gradually the problem started happening again.
- Reinstalling my system software worked for about two days.
- My most recent "fix" was to change the configuration of my
sites within DW. Up until now, I've either been accessing files off
of a network drive (directly, not from within a defined DW "site),
or through a DW site where the local folder was a network drive.
When I copied the files from the harddrive to my desktop and opened
them in DW, I didn't have any problems. I was also able to get a
co-worker who has a brand new MBP with a fresh install test and
confirm the same problem.
I found this today -->

which is old, but once I changed my site configuration so that the
local folder was something on my HD and the remote folder was the
network drive, I haven't had a freeze once. Now, it's only been 2
hours, so I'll reserve my excitement.
