I first encountered a problem with the flash security patch in my own .Net software. It depends on IE delivered from the operating system. Any site using flash gave me a unhandled exception. I removed the patch from my main PC and it is OK, although any users will have problems.
I then thought it may occur with IE11. So I started IE using a virtual PC that had the patch applied. Went to the web page listed below, same one that gave me the error on my PC. The page gave a security warning. I chose to 'show all content'. When I did, all seemed ok, so I went about doing other things. I went back to the Virtual PC later and sure enough, the same break point error occurred. Was able to reproduce twice. Here's the page:
