Help!

I am having the hardest time trying to get blog entries posted! Pictures sometimes load, then sometimes won't. It hangs up. I can't scroll using the bar on the right. I can't do anything! I spent probably a good hour typing and uploading pictures (painstakingly) and then the blasted thing froze up and somehow didn't save anything! It is very frustrating and I can't figure out what the problem could be. I've upgraded my internet explorer. Anyone have any ideas???
