I have only launched it once, not even progressing to selection of "buy" or "demo" options because I wasn't impressed with what it looks like, what config options it offers, what info it says it will provide, and of course, the excessive price.

But now, it acts like it owns the joint! It aggressively launches itself from time to time without being asked and, most egregiously, it set itself as the default for opening PDF files!
