have converted an Access97 to Access2003 (in 2000 file format) - much is
working ok but some command buttons are throwing the error:

Error Number 3420 - Object Invalid or no longer set

Have browsed around becoming educated on that....have looked at:
http://allenbrowne.com/ser-48.html#conversion

It isn't opening the VB window & showing me the compile line error - just
that message in an error box....so am wondering if anyone out there has run
up against this specifically and/or whether there is a method to zero in on
the trouble line of code.....

right now I suppose it is the 'OnClick' event code - but as there is alot of
code back there calling functions - including opening another form...it could
be in the open form or subform properties too I suppose....wish one could
focus in more easily on the trouble cause......

advice definitely welcomed...thnx...NTC
