Power Recycling to fix Freezing?

I too have a m240 that is frozen on the main screen. Tech support told me to do the following and maybe it will help some of you:

If all else fails, we recommend that you perform power recycle on your m200. This is to drain the MP3 player of excess power, thus making it work again. The procedures are as follows:

1. Take the battery out of the Sansa m200 player.
2. While the battery is out, plug the Sansa m200 player into a USB port, preferably a rear one or a self powered USB hub, on the computer.
3. If the screen is blank, try a different USB port. If the computer is a laptop, try this procedure on a desktop before moving on to the next step.
4. If the screen reads ?USB Connected? when the Sansa m200 player is plugged in with no battery, unplug the Sansa m200 player.
5. Hold the "Menu Button" (Power Button) for 45 seconds.
6. Connect it to the computer again (still without the battery).
7. If the screen once again reads ?USB Connected,? disconnect the Sansa m200 player and insert a new battery which has never been previously used.
8. Try powering on the Sansa m200 player.

If the above procedures (power cycle) didn't work, please repeat the process again but now hold the power button for 2 minutes and wait for at least 5 minutes before plugging in new set of batteries.
