gots the same porblem on my 99 ex dude... its not that hard to put the window back in the railing but like u said its a pain......it seems like the rubber guiding thing on the railing inside the door tends to wear out i guess... i tried wd-40 on the railing and it helps for a while. just lube everything up. it only falls off the rail when i put the window all the way down. so i keep it half way for now just in case it does happen. dont wanna be taking apart the door panel @ the mall or something u konw?
