Hi,

I apologise yet again that there are two bugs in TAL for Windows
3.0a that affects accuracy of results. I have released ver. 3.0b that
fixes these bugs:

1. Bug fixed in Range Lookup: Silt class was mis-specified for the
USDA and Canadian schemes. This is a minor bug because it only
happens for extremely narrow ranges.

2. Bug fixed in Point Lookup: Sand values were mistakenly taken as
Silt values, and vice versa. This is a major but blindingly obvious
bug! But how it got through my debugging sessions, I don't know!

I was perhaps a little too over-confident in releasing such a major
version without debugging it thoroughly enough. Ver. 3.0 is actually
a version in transition, in preparation for the feature whereby users
can add or create their own classification schemes (ver. 4.0). Also,
ver. 3.0 has completely revamped its graphical user interface; again
in preparation for ver. 4.0.

You can get the corrected version 3.0b from here:
