1. Take an X5 with a CF card installed, but not an SD card.
2. Set the system time to 1 minute before DST, which is April 1, 2007 1:59AM
3. Turn the unit off and wait
4. If you watch the screen, you will see it flicker on and back off when it hits 2am.
5. Power the unit on
6. Do NOT acknowledge the messagebox stating the clock has been updated
7. Open File Explorer and attempt to open Built In Storage.
8. The unit will hang and never open BIS
9. Pull out the CF card and it will open it right up

This is NOT present with PPC 2003, as I have tested it. It will not happen if the CF is not plugged in. It will not happen if you acknowledge the message.

Ever heard of this and any idea of a fix? Don't tell me to click the messagebox because I can't. This is a standalone program that buries the messagebox.
