ADT2004 and 2005 conflict

My office is in the process of starting to migrate to 2005 from 2004, and I'm finding some errors occuring that defy explanation. A code statement that has worked fine in 2004, after installation of 2005 starts playing up. An example is a line of code like this:

Public Sub ChangeProfile()
Dim preferences As AcadPreferences
Set preferences = ThisDrawing.Application.preferences
' Change to a vaild Profile name
preferences.Profiles.ActiveProfile = "MyProfile"
End Sub

The code works Ok most of the time, then fails at the application, so I can't set the preferences object. It only works if I do the full statement like this: ThisDrawing.Application.Preferences.Profiles.ActiveProfile="MyProfile"

Is there any reason for this? Its a bugger to deal with as there is apparently no reason for it and how would I test for it anyway?

 

Wrong group, dude.

This is for AutoLisp only.

 

Dang. Guess I'll have to repost.

 

The group name is .customization. To me that means any customization query,
lisp, VBA, C, linetypes, Hatches, Menus etc. Everything that the "Help" system
lists under "Customization." If I am in error I pray the powers to rename the
group and set up another for all unlisp questions.
