I don't normally say much in threads like this, but there are a multitude of reasons why so many users still rely on P4/PP. Some of them have been mentioned, some have not. For myself, I reluctantly use P5 now. The primary reason for use is the nested folders and separate runtimes. It's much less hassle for me than the old ProPack/PBooost combo. Yes, I still hate the fact that I have to change my screen resolution to use it. As for P6 - well, I own it, and it seems to work fine BUT every single time I use it I wind up with corrupted files on drives where P6 is NOT located, in folders that have no reason to be accessed by P6 (in one instance it was my web browser that was corrupted, in another instance it was the entire contents of my d:/ drive.) I can't PROVE that P6 is the cause of the file corruption, but since it ONLY happens when I've opened P6 (Yes, just OPENING the program causes the corruption) and I've gone so far as to remove and re-install the program just to be sure it isn't some other application doing the damage, I'm fairly certain that P6 is the culprit. So, as long as things like that continue to occur to those odd few of us out here, we won't be "upgrading" or "moving on" to the latest and greatest versions.
