>I had to do something similar, except that I went with an invisible button in the container on top of the label and image. I don't have this problem and the invisible button makes the whole thing look more like a normal button when it's clicked.

In case you need to do this someday...

Next came another odd problem -- I had to disable the "button" for some situations, and the only way I cound find to get a "natural look" for a disabled toolbar button picture was to use a button in the container instead of an image.

So, I put a small picture command button inside another container to cover the button's edges. I then place the new smaller container inside the big container where the image was, and programmatically enable/disable it as needed. Works great, but whew...I hope the users are happy after spending a couple hours on this :)
