Here's the "browser freeze" issue in-process.
I capture video... and the browser profile.
Notice that I cannot click on anything... except when I eventually move the cursor over the top right menu items...
Home / About / Contact
the cursor changes from a finger / arrow to an I bar.
Even though the cursor changed... I could not select or do anything.
The issue ended when when I realized I could right-click and I selected view source
I tried to attach the cpu profile... but the forum would not let me. (unauthorized file type).
Will send pm instead.
