Dick,
Had you mentioned your impairment in the OP, it's probable that you would have gotten a more sympathetic reaction, and perhps some attempts to help you overcome your issues. My wife is a kindergarten teacher, and she deals with kids with various types of learning impairments, or clinical issues like ADHD and Aspergers. Not the kid's fault, but something that can be dealt with, via tutoring or meds. Unfortunately, it's inappropriate to give you any 'diagnosis' in the absence of professional credentials or personal evaluation, but recognition and acknowledgement of a problem is the first step to a remedy!
Telling you to 'pay attention to the settings' is simple, getting someone with issues to do so requires a remedy to the fundamental issues, not pedantic comments from folks like me!
