Steps to reproduce the problem:
1. point to any "clickable screen element"
2. click
3. highlight but no activation of the element

What is the expected behavior?
the element responds to the click with the expected action

What went wrong?
Essentially I'm having to click between 3-5 times for various screen elements to interact with any on page element.  If I am very deliberate and slow, and press down, hold for an entire beat, and then release the element often works, but just a regular click (one that works in every other application and even in Safari on the identical page) it works fine.  I suspect you have a debounce or other technique that is causing the events to miss fire or not be registered.

Did this work before? Yes I cannot say, it's been a problem for about 2-3 weeks now.

This is almost debilitating, and I'm about 2 days away from uninstalling your Browser and going back to Firefox or Safari.
