Smartcrawl gives false positives


I installed Smartcrawl and it says that I have about 70+ 404 errors. But I’ve checked 1/3 of them thoroughly and none are 404s. The pages exist where Smartcrawl says that the links are broken. I haven’t checked the other 2/3 thoroughly but I did randomly check about 8-10 more 404 errors and none of them were broken either.

Here’s a Screencast:

So, what should I do? I don’t really want to go through the rest of the 404 errors. But, more importantly, these false positives erode my confidence in Smartcrawl results. And I fear that in the future, I will have a 404 that will pass by me unchecked.

Can you help me correct the problem?
