Acrobat standard 9.0 error while enabling commets option using Java script object

Question

I'm using the below java script code in my VB 6.0 application for enabling commets options in the PDF file
Dim oJSO As Object
Set oJSO = mPDDoc.GetJSObject
oJSO.Collab.showAnnotToolsWhenNoCollab = True
It is working fine till Acrobat 8.0. Now I'm trying with Acrobat 9.0 standard edition, it is throwing scripting error 'An unhandled Win32 exception occured in Acrobat.exe[308].
Can anyone suggest the way to enable 'comment' options in Acrobat Standard 9.0 using Java Script Object?
Thanks

I get much the same problem with VB6, Acrobat 9 Pro and WinXP SP3. When I single step the line:
oJSO.Collab.showAnnotToolsWhenNoCollab = True
in debug I go to the error handler for my Sub. Inspecting the VB Err object has Number = -2147417851 and Description = "Automation error
The server threw an exception." I get a Microsoft crash notice about Acrobat a short while later.
I've experimented with the JavaScript debugger in Acrobat and you can execute Collab.showAnnotToolsWhenNoCollab = True and reference the value of Collab.showAnnotToolsWhenNoCollab in the console. The problem appears only when accessing Acrobat Javascript through the Interapplication Communication API.
If anyone can help it would be appreciated. I tried Adobe's Acrobat support and they were no help at all.
