Anyone know the answer to my question about transparency?

1. Which directory should the font .pe file be placed on the SD card?

2. When using the Load Font command, should the extension ".pe" be included or excluded in the string?

3. After using the Set Font command, how can you go back to the default font later?

Thanks.

Are the calculator buttons in the video using bitmaps with transparency channels?

I did the firmware upgrade last night and tried the splash screen upgrade several times to no avail. Still just get a white screen. If the unit worked properly, about how long does the unit require to upgrade itself? Is there any indicator that upgrading is taking place during this time?
