Just wanted to say thanks. I used the technique here xxx.audsound.net/_share/bbtb_select_fix.pdf with some variations to correct the track ball not clicking on a Bold 9000 and it worked.
I did replace the entire track ball as well since it was dirty, ordering the replacement from ebay.
I did clean the small dome contact with a pencil eraser first and then rubbing alcohol and the same for the contact underneath.
I also replaced the original tape holding the dome down with 3M scotch tape. While I peeled the original tape off fine, It wasn't going to stick back on.
