Why so many initial problems?

I agree that there are many threads raising issues; however, I think it is important to keep in mind those of us who do not have issues are not creating threads. I would even dare to say that if a poll were taken the majority response would be "no issues" or "one/two small issues". I myself have had a near perfect success rate since installing the fantastic PMDG 737NGX. In fact I have only had three issues to be precise. One was not setting the G/S in the FMC, one was not setting my IRS switches to "NAV" (that was embarrassing), and the last is an issue with the plane jumping when flipping to HDG which I believe the PDMG team is working on correcting(?). So, I will stand up and say this is a ground breaking plane. The only thing that upsets me is I have to buy this other addon software called MS Flight Sim X to run it.
