Someone else on this forum brought this up already -- I can't remember who
exactly: but I agree with that person that it seems that all values smaller
than -99 for a* and b* in the Curves dialog box get their last digit cut
off, so that, for example, -103 and -108 both appear as -10, and so forth.
So, possibly, the numbers *inside* the application are correct, but are just
*displayed* incorrectly. In any case, the problem should still be fixed.
Best regards.
