After asking for any idea's concerning how to customise my blog I was given a few idea's but with no success, it still kept freezing, but I did a bit of thinking, no it wasn't a strain on the ol brain :-) I searched on line and came up with this solution. All I did was to download Mozilla Firefox. I was then able to open up my blog and go to customise-advance and make all the changes that I wanted without it crashing.
I have been back to try it out again and I had no problem with it.
I hope this will be of some interest to any bloggers that are having this trouble.
