Quick Mask not working???

[dietcokegirl]

I am using CS4.

I am trying to use Quick Mask to temporarily select a specific area of the picture. After highlighting the area with the brush tool, I click on "Q" like I always do to select that area. However, instead of just selecting that specific area, the entire picture gets selected??? I have used this function many times before, but never run into this problem.

Any ideas on what to do about this?

I have re-started the computer several times over the last few days and the problem continues. I have also tried selecting different brush sizes and that has not helped, either.

I appreciate any suggestions or advice you may have!

Have a great night!
