Mac OS 8.5: Proper Driver For Umax Scanner

After performing a number of sofware updates to my iMac, my Umax Astra 1220U scanner doesn't work. When I try to use the scanner software and preview an image, the scanning bar moves slightly and then my iMac locks up, forcing a reset.
The original Astra 1220U driver was VistaScan 3.0 which doesn't work with Mac OS 8.5. Version 3.1 is available for download from Umax.
