Help integrating PHP w Dreamweaver

***Apoligies if this is not the
right newsgroup for this posting***

I have used Dreamweaver for about a year, and I'm now starting to learn PHP
and MySQL. I have a couple questions about the environment. My MySQL and
PHP setups are working great; my code runs fine. But there's something I've
missed in the Dreamweaver setup. I'm using IE 6.0.28, DW MX, IIS, Win XP
Pro. Apache is installed, but I disabled the service since I've never used
it before.

1. Why is it that when I'm in a PHP page (*.PHP) all of the Panel group
buttons are greyed out? If I switch to a *.htm they become active again. I
mean, I should be able to click a comment button for goodsness sake. The
books I'm going through always put PHP in the HTML page; does DW expect it
to be external and just INCLUDEd?

2. I added v. 2.5.0 of the PHAkt extension to get PHP server behaviors, but
I don't see any right-click support and the "Debug" panel in the results
area is always greyed out saying. If I edit the site and set the site
Server Model to PHP MySQL or PHP ADODB the debug panel says "There is no
debug extension registered for the active server model". I'm not sure what
I should be seeing, but I expected a bit more integration than this.

3. I installed a PHP CHM file in the help folder but there is no integrated
PHP help.

4. After I check a PHP page in the external browser a few times, F12 no
longer works and the menu items is greyed out; I have to open the page in
the browser manually.

5. On that note; my PHP pages will only run when the path in the browser is
localhost, not my IP. I have changed the testing server paths etc., but
when DW takes my page to the external browser it always uses the
c:/inetpub/wwwroot/... path and I have to change it.

What am I doing wrong?

BTW: I am now going through the PHAkt tutorial ("pgsql" website/database).
Everything is going well, all the code works but the buttons etc in
Dreamweaver are still greyed out.

Thanks
