Blackberry Timer Issue

Hello-

I'm new here, I've tried searching for this issue before i resorted to posting myself;

The Timer on my blackberry 9000 no longer seems to reset properly. I've set my timer to 99 hours by accident, I was trying to set it to 99 seconds, and now when ever I try and set it to any sort of time it just adds the new set time on top of its current count down time.

I've tried to press the reset button and then set the timer, that does the same thing.

Is there something wrong with the software, or is my blackberry timer cooked?

Thanks in advance.

My Device Info: BB 9000 os 4.6.0.162(platform 4.0.0.155)
