I'm using the NVBrowser.cws example project listed in the help.
On one computer, the call to NetworkVariablePopup returns a -90 which (with the help of GetGeneralErrorString) gets decoded to: "The attribute value passed is not valid".
This is an odd error, since the only attribute for NetworkVariablePopup is the pass-by-reference pathname.
Now, on another computer, NetworkVariablePopup is working fine in the same project. What is the problem here?
