Problems scrolling and clicking

I am using the latest Safari build and I am hitting more and more problems clicking on things, scrolling pages and such.

Especially nested div withs buttons and so on. Updating to the latest was a mistake but it came part of the software update.

Unless this gets fixed I'll need to switch to a different browser. It works about 1/2 of the time; at other times the items you need to click or hover over are offset on the screen to the corresponding positions where the mouse is active or the item highlights. Sometimes it's below and sometimes above. In addition the browser can't always enable the scroll bar correctly although resizing the windows shows the approriate indication where the scroll area should be and how far you ought to be able to scroll down but you just can't.

When will this be fixed?
