id like to know if there is any way how to change the color of the main window ...
cus when i change the color scheme of my win xp explorer windows are all the same color but MSN messenger is still light blue 
for example Windows MEdia PLayer has nice enhancement for choosing different colors . .
i wanted to know if its possible to change messenger color like WMP-s

I don't think that there is a way without patching MSN Messenger, and patching is illegal. There may be a patch somewhere out there, but it's doubtful because of possible limitations.

Although, I can remember that there was something being made to do this job, except they couldn't do it correctly and it kept going wrong, I think the idea was scrapped though...

So I'm afraid that you're out of luck this time ...

You can already change the colour of the conversation windows, so there's nor eason why a plugin can't recolour the main window.

i think skins are the better solution for this till yet....
