Block Cache - Issue?

I've been making changes to various Blocks through Block Management and have noticed a peculiar problem. Or maybe its supposed to work this way...I don't know. But after I make a change to a Block, such as remove or edit the contents. I need to Delete the Cache for the changes to take affect on the appropriate page. I noticed this same issue with the Photo Album, to get Thumbnails to appear I had to do a Clear Cache before they started to work. This isn't a major issue, if it is even an issue. But if someone could give me some direction, I'd appreciate it.
Am I missing a setting somewhere? Are Blocks supposed to work this way? I have verified my CHMOD on the cache files. Any thoughts would be greatly appreciated.
