You should run the IB compatibility check for the version of the OS 
you're targeting. It sounds like your button images are set to scale, 
which isn't supported prior to 10.5.

Open your nib and click the "info" button if you're using IB3. Then 
set the target OS. If you click on the entries, it will take you right 
to the source of the problems. If you're not using IB3, select 
"Compatibility Checking..." under the File menu.

But, basically, buttons can't scale images except on 10.5. You need to 
do it yourself for older versions. It probably makes sense to just pre-
scale the images in a graphics program.
