Problems with WHERE clause in Query builder in Toad for Oracle 9.0.1 and Toad 9.1 (4317071)

Added a condition to a WHERE clause with the alias name in Query Builder and saved the DML file. Then after closing Toad 9.0 or 9.1 and opening it again, the alias in the condition gets lost.

WORKAROUND:
None

STATUS:
Waiting for fix in a  future release of Toad for Oracle.

Sample of the 'where clause'
WHERE ( (fstm.a = fasr.a)
AND (fstm.b = ffar.b)
AND (fstm.c = ffis.c)
AND (fstm.d = fstt.d)
AND (ffir.e = ffis.e)
AND (ffsi.f = fstm.f)
AND (ffsi.g = ffir.g)
AND ( (.h = 1004932919575) ) )
It should be fstm.h = 1004932919575
