You know from all the problems with Adobe Reader freezing up, crashing, and having font/text aliasing problems depending on size setting of the page nothing frustrates me more than opening those rare PDFs from Intel and a few others where it completely disregards the user preferences and resizes the window to fit the PDF document size and repositions the Reader window to the center of the screen. And of course requires me to resize and reposition the fucking thing so I can actually read the PDF document on my 1080p monitor every damn time I open those PDF files. Naturally there doesn't exist a configuration option to prevent that crap from occurring.
For those PDFs I have to open them through SumatraPDF, but I don't know about those troublesome PDFs until I accidentally open them through Adobe Reader. The only downside to SumatraPDF is that it lacks a proper advanced Find/Search window like Reader's so that it can list all results at once instead of me having to keep pressing next to find the section of the document I'm looking for.
