Yup. I noticed that recently, and using the new one changed things for the
better.

Certainly. I have a few people on the list, and will be sending off the
binaries to them after fixing a coule more buglets that were pointed out to me
by a VERY efficient beta tester.

I am getting some strange things too. My best beta tester has determined that
the data read seems to come up a little short sometimes. In one case, 3 bytes
seemed to be dropped, which threw out the positioning of the block buffers and
caused the program to not recognize a file header. Additionally, With heavy
disk activity, it seems I can hang the driver, as you have.

Isn't it though?
