I was going through the review queue recently and still seeing a lot of tech support close votes which seemed completely on-topic with graphic design and didn't require access to a specific setup or file. Wrzlprmft did a stellar job 10 months ago with the Revisiting closures series. Among the series, the one about tech support seemed to be fairly straight-forward and reaching consensus (as opposed to broad questions for example).
So I'm a bit puzzled: Do we have any idea as to why tech support close votes on valid questions are still coming in regularly?
Here is a framework that I like to use when trying to understand/fix behavior-based issues. It could be helpful on reflecting about other issues as well.
