Although I am not switching back just yet, I am with Tim on this one.
The PDT 2.0 is the worst release ever. I am not saying this to
discourage the people who are putting in time and effort to make the
PDT, I thank you guys and girls for that! Without it my day at the
office would with out a doubt be that less fun. All that being said, the
PDT 2.0 is to slow on completion and most of the time it does not work
in projects badly coded. The $this bug is the most noticed. I have
disabled most auto features with has made it much more responsive.
