words wont wrap in label.

hi,

i have a long contigous words displayed in a label, now i want it to be wrap. 

i tried the white-space:normal, and also tried setting its width, but they wont work.

in IE, the words get wrap (btw,some text are cut) but in mozilla FF it wont.

 for example:

from this:

MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM...

to this:

MMMMMMMMMMMMMMMMMMMMMMMMMMMMM

MMMMMMMMMMMMMMMMMMMMMMMMMMMMM
...
