Has anyone found a decent way to keep the SD card from poping out of the unit short of using a case that blocks it. I have not found any case that I like so far so I use the Treo bare back

and keep it in the Sedio belt clip (face in design), this all works fine for me but that darn SD card just loves to pop out on me. I put a piece of tape over it but that look like crap. Any other ideas...?
