I've copied (using the built-in copy function or the installer)about 10-15 programs to my SD card. I do not use any custom launchers.

The program icons fill more than one page on the screen. Whenever I try to scroll down using the 5-way to see the additional programs, my Treo resets.

I copied everything off the card, reformatted and copied everything back. Still get the resets. Other than this, the card works fine.
