Just a heads up for Incra jig supplier Professional Woodworking Supplies, who is a forum sponsor:
If you click the little advert for PWS on the right hand side of desktop screen, in the column of forum sponsors, you get a new tab with 404 - File or directory not found.
This was in the main forum home page. Oddly, the problem doesn't happen if you click the ad here from the incrajig subforum page. Might pay to go through more forum pages to check. :)
