trackball problems inevitable?

i've just gotten a 8900 curve and everything was perfect even the trackball was good, then suddenly tonight it collpased to the extent that when i press lightly on the ball it sinks..

i dont think it is suppose to do that cos i remember earlier tonight it wasn't.

does this happen with everyones blackberrys?

the functions and everything work fine the problem is that when i use the trackball as a mouse scroller in the browser it's less responsive as it was previously..

would changing it really work or will i just have this same problem again in future?

Mine never stuck but it was pretty hard to navigate with once so I took it out and cleaned it - right after that I ordered replacements just in case. Now I have a few on hand so if I botch something up while cleaning or it just breaks I am covered. You can try to clean it to see what that does. Its quite simple

its not actually stuck but it collapses when i press lightly on it.. i think it's suppose to to be hard when u touch lightly..

has anyone else got this problem on their 8900?
