Of Tags and Labels

Can anyone help me find a way around this?

After playing around my labels for a bit, I realized that they weren't working the way I expected them to. By clicking on one of the tags listed on the right side of my blog, I anticipated that the page would show all entries posted under that particular tag. Unfortunately, this is not the case. What the page shows are entries that were posted under that tag only for a single month. That kind of defeats the purpose entirely. Can anyone help me find a way around this? I would NOT like to use Blogger beta at all.

P.S. And while we're at it, I just discovered that my site looks really crappy when seen in other computers that do not have the fonts that I use. I'm going to try and find out what these fonts are later (as it's 4 in the morning and I still have to study and I just feel so goddam tired), and I'll post links so you can download them. So that you'll see what the site really looks like with cool fonts and everything! :)
