Definitely not an uncommon problem, especially if the BB is carried in a purse or pocket with no case to protect it.
Besides, if it is a trackball/lint/dirt issue, doing the wipe will not resolve it. If it is a software issue cleaning the TB won't resolve it.
Another help can be pressing in the TB and blowing compressed air into and around it.
It could be a TB replacement might be in order and that is not hard to do and is very cheap if DYI....If moving it around and the air helps she might consider replacing it (the TB) because moving it around only displaces the dirt/lint. It doesn't get rid of it.
Hope it helps....
