Digital BW, The Print

I just allowed an update to Mac OS 10.2.3 today and have given myself a 
large headache.

Firstly some history.  Ive never been able to launch OS 9 Classic under OS X 
without it crashing before launching, however, I tried again today with OS 
10.2.3 and the process prceeded further than usual, suggested it needed to 
update some OS 9 resources to which I agreed and still crashed - end of story 
I thought!

Later today I rebooted in OS 9.2.2 as usual, opened Photoshop 7, loaded an 
image and selected Piezotone B&W export plugin but this time all got was the 
Epson (1160) driver box. Even a reinstall / re-boot didnt change anything.

Does anyone have any idea whats gone on here....
