It is a bit off-topic, but that timed import on a new install should really be an Opt-In choice, not an Opt-Out.
Then it could either stay in the Action Windows area with a question like "Do you want MC to import all media files found on your computer and connected drives?: Yes/No" until the user answers the question, or it could just have a very long time-out, like five minutes. Either would give the user time to work out what is going on, and decide what they want to do. If they say Yes, MC imports everything. If they say No, MC opens the Auto Import dialogue, perhaps with a message to "Please configure your import options".
The 45 second time-out and then MC imports everything it finds, everywhere, isn't a good thing.
This has been discussed before. I think it is time the answer changed.
