I'm sure this will be a regular feature (web site rants, that is).
The support web site for Canon printers (and probably other products) has a search timeout. I was trying to find some helpful information about how to get my Canon Pixma iP1600 to actually feed paper, instead of just grinding for a while. It's never been very good at doing that. I went away from the computer for a few minutes to see the block structure one of my daughters built. I come back, and the search session has timed out.
There are lots of web sessions I want to time out (my bank account comes to mind). But a search in the printer knowledge base? What's up with that?
