430	Estimate does not handle unknowns as it used to do	jimarin	Víctor de Buen Remiro	"Using tolbase/tol version 2006-09-05 (and also reproduced for version 2006-09-22)
we have experienced the following:

* having unknowns in the data produce errors when processing estimate function.

* the unknowns are not corrected and they appear on all estimation series (residuals,etc...)

And

* this does not happen when using older versions like 2006-08-17

Item more: the behaviour of tolbase.exe seems to be different from tol.exe, some times the error appears for tol.exe and does not appear in tolbase.exe.

An estimate isolation file has already been given to josp for his study on this, and the same file could be given on demand to any developer that should look onto this problem.

The problem is labelled as major cause our application typically deals with series with unknowns.

Perhaps it is interesting to note here that this error seems to be going on since bugs 424 and 428 were solved.

Thanks.
