#18 Modifying table columns errors or shows no errors

[Technical Support]

I have a table named 'Users'. I have a field named
Login_ID. It was originally varchar(50). I just wanted
to change it to int(4). When I tried to save the
changes they would not save. However I was able to
change other fields in the table structure from varchar
(50) to int(4). I did move the position of the Login_ID
field from it's original ordinal position so I don't know if
this may have an effect on the bug.

Also, repeatedly there are problems with the ASP
Enterprise Manager when modifying columns with indexes
on them.
