I am using a 2011 Macbook Pro core i7 2.0ghz and Safari 5.0.5 is acting strangely.
Firstly, sometimes when I am on youtube the video will keep playing but I cannot click anything on the webpage. The whole page is unresponsive. I cannot scrub through the video, pause it or click any links on the page. I loaded up the same page on Firefox and it works fine.
Also the above happens on google too. I typed in a search and hit enter and nothing happens it didnt register that I had clicked search or hit enter.
Secondly sometimes the webpage will hang and not load. It will load up about a inch of the blue loading bar then hang and nothing happens. Other occassions the grey spindle by the refresh button will just spin endlessly and not stop.
I have had none of these issues on Firefox on the same webpages.
OK now it seems Safari is not functioning on any webpage. I just tried Play.com and Amazon.co.uk and the search function is not working at all. I type in a search and hit enter or click the search button and nothing happens? It doesnt register at all. I can click links to products on the same page though.
