PowerBook G3 and ViaVoice OSX problems

[kaimanl at attbi.com]

Greetings,

I have a PowerBook G3 with a 400 MHz processor and 320 MB of RAM. I 
am able to run ViaVoice in OS 9.2.2  but not in OS X (10.2.6). I have the 
latest upgrade for ViaVoice in OS X (10.2.2) and have tried uninstalling 
and reinstalling the application as well as checking the drive with Disk 
First Aid and correcting the verifications. When I try to launch the 
SpeakPad it says that it can't open the VoiceCenter. When I try to open of 
the VoiceCenter I get the spinning ball which never stops and I have to 
reboot the computer. I am not able to force quit the application. I am able, 
however, to perform ViaVoice SetupAssistant but that's about it. The 
sound input is correctly set to the USB microphone that came with 
ViaVoice.  

Any suggestions? Thanks.
