Im having some huge problems with my template...

First problem is the dissapearance of the left and right border from my center block.

It shows up normally in firefox, but it dissapears in IE.

Second problem is the stretching of my template when I goto my message board. It's an Invision board for xoops, it doesn't stretch up my design in firefox, but it does in IE. Any idea how I can adjust this ?

Another problem, not template related but still hard to figure out. Whenever I create a block, and not let them show up for all the pages. It dissapeares from the block admin... How's this possible? When i create a new block that shows up on every page in the site, it does appear in the block admin.
