Yes, I know it sounds like a VB problem, but it isn't. I wrote an app using the version of the Listview and Treeview controls provided with the Office 97 Developers Toolkit. These are in the comctl32.ocx library, version 5.0 (SP2). It worked fine. I have recently installed Visual Basic 6 Enterprise Ed. on my computer, which brought with it version 6.0 of comctl32.ocx.<br><br>Now when I go into my app, the forms work fine. But in design mode, if I access the property pages for the listview and go to the Columns tab, Access crashes horribly on me. I can create a new listview control in either version, and they work correctly, but the ones already on there just cause the system to crash.<br><br>Has anyone seen anything like this, or does anyone have any suggestions?<br><br>Cheers,<br>Jon <p> Jonathan<br><a href=mailto:j.w.george@virginnet.co.uk>j.w.george@virginnet.co.uk</a><br><a href= > </a><br>Working with: Visual Basic 6, Access 97, Visual Interdev 6, VBScript, Active Server Pages, SQL Server 6.5, Oracle 7
