Just a bit of a warning to the 'mister cee': I wouldn't try other bootskins. I had the same problem in that bootloader sometimes wouldn't load the skin. I applied a new skin lately and since then ran into a serious problem upon a reboot. Now my Log-On-Screen won't load at all, making it impossible to start up windows. Strangely enough, I did try loging out- without a problem. Right now I'm fighting to get my windows back to working condition- as of yet with no success.
I had the same problem that sometimes skins wouldn't load- and even though I'm not ABSOLUTELY sure that this problem is because of the altered login, I suggest you don't take the risk of not being able to log in.
