Trackpad option/settings missing on MacBook pro

Hallo.
When i go into Trackpad (in Danish pegefelt) setting, the field is blank? No options to choose from.
Tried to reinstall snow leopard, and then it works, but just for at little while, then i turns blank again.

Anyone have a solution for this issue??

It´s a MacBook Pro 13" mid 2010, with Snow Leopard.

(Did upgrade to Lion, but returned to snow Leopard again, så don´t know if that could have anything to do with it???)

How did you revert to Snow Leopard, was it a clean install from disc that came with your Mac? Also, did you try repairing disk permissions from the disk utility app in the utilities folder?

Did make new partition, where i installed snow leopard, and the i deleted Lion. It works perfectly, the only problem is the missing trackpad settings..
Did not try to repair the permissions from the disk utility.

I am also having this problem - did you perhaps manage to sort it out?

The same problem occured
