I'm unaware of whether this is just an issue of Safari 4 being buggy or not, but ever since upgrading to the beta i've had to reset my connection to my network (via Network Diagnostics) every 5/10 minutes due to web pages refusing to load. Once the connection has been reset the text of the page fully loads but images so not. This problem then clears up for another 5/10 minutes before recurring. I've tried reseting my router but to no avail. Any suggestions fully appreciated?
