This is a minor problem, but it's annoying.
I have both Acrobat 6 Professional and Acrobat Reader 7 installed.
In Windows Explorer, the default action for .PDF files (including Handbook.pdf) is to open within Acrobat Reader 7.
However, when I launch the handbook from within PowerTools, itself, the handbook is opened with Acrobat 6, in editing mode!
OS: Windows XP Professional SP2.
