Using treeview.htc results in DLL initialization error

[Guest]

We are using Microsoft's treeview.htc control (part of
Microsoft.Web.UI.WebControls) to display a tree control in
our .NET application.

When displaying the tree, the browser returns the error:

Dynamic Link Library (DLL) initialization routine failed

pointing to the following line in treeview.htc:

if(oItem.filters.length>0)

in function blurFilter().

Does anyone have any ideas about this and how to resolve the error?
