Line wrapping broken on Bash 3.0

I just installed my first LFS 6.1 (yay me!), but am having a few problems. The biggest one is that the line wrapping isn't working properly on bash. Whenever I type a line that is too long (haven't counted the exact number of characters), it wraps before it gets to the edge of the screen (about 3 quarters of the way), then wraps back to the same line it started from and starts writing over the prompt and the beginning of the line. After the first wrap, it seems to work properly. I compiled bash exactly the way it said in the book, including the patch which is supposed to fix something like this. I recompiled it, but still have the same problem. It even happens when I chroot from the livecd! Any ideas what might be broken?

Maybe a PS1 issue ? try export PS1='$ ' just in case

Yep, that was it. It seems the color codes in my prompt messed it up. Any ideas why? Knoppix and the LFS livecd both have colored prompts, so why can't I? My prompt currently looks like this:

Code:

export PS1='\033[1;36m\u@\h\033[1;37m:\w\033[1;32m\$\033[00m '

I recommend you using tput to colour your bash prompt.
you should check this art:

Bash doesn't realize that the color codes don't take any space unless you escape the color codes: \[\e[1;36m\]
