One HTML file being ignored as a link target?

I just noticed a really weird behavior in one of my DW sites (actually my own personal business site).

I have an HTML file named “Services-Print-Design.html” that displays fine in DW and when previewed by itself in a browser. The problem is I have several images and even menus in my site that should launch this page when clicked… but nothing happens at all? Hovering over an image or menu button recognizes there is a link before clicking, but clicking does nothing? For instance, I have 6 identical JPEGs on my Home Page and each links to a separate HTML page. Five of the Six links work perfect when clicked in Preview (same when selected from alternate dropdown menu). I have spent 3 hours making sure the code is identical to the other five page links. The page itself shows no errors in code view. I tried renaming the file and updating links throughout the site - no effect? It behaves like that page is just preview-cloaked? If I click on the file in DW and say “Show in Finder”, that works perfectly.

Now for the real mystery, I have not made any revisions to my site in months (or inside DW), but the same files I uploaded to the server months ago are working perfectly! ALL the links online launch that same page fine, so this is just happening when “previewing “ in any browser. from DW. It is happening on both my Mac Pro (Sonoma) and MacBook Pro (Tahoe) both running latest versions of DW?

None of my other sites in DW appear to be having this issue, just MY site (with that one page)?
