Thanks. There certainly were some rounding errors. I was working on this earlier today and fixed many of them, but there is one left which is a bit harder to fix -- the "amount edit" widget (which is used extensively) will internally truncate decimals. This means that I can set a value to, say, 10 decimals but it will truncate it to 6.
As I said, I've fixed most of the issues so far (although I'm still testing the fixes). Your particular test case, for example, has been fixed (there was definitely a truncation issue). I'll take more of a look in a few days when I get some time again. -derek Daniel Hannum <[EMAIL PROTECTED]> writes: > sorry.
