Any way to keep clock always-on-top on Blackberry (Pearl 8120)?

[sufue]

Hi all -

Does anyone know of a way to get the clock to always show in the Mobipocket app for Blackberry Pearl? I often lose track of time while reading , even on my tiny BB screen, and would love to be able to see the clock without having to exit and then re-enter Mobipocket.

Or, does anyone know of a third-party clock app that has an option to keep the clock "always-on-top"?

Any help much appreciated!

TIA,

Sue
