How do I enter text on my PRC-100?

I think I've tried tapping on nearly everything on the screen, but no virtual keyboard pops up.

I've checked and I have the latest version of s/w (I can listen to Yamaharadio and my piano 
plays).  Here's what's installed:

Embedix Plus PDA v 2.0
Opera Browser v 6.0
Insignia Jeode Java v PDA edition
Qtopia for Embedix Plus PDA v 1.5.4
Linux Kernel v 24. 18-rmk7-pxa3-embedix
ROM v 1.20

At some point I think this worked, but that was 2 weeks ago when I first set it up.  Appreciate 
your help on this one..
