SelectDirEx/SelectDir setting network path

[elneln]

I have an Installscript project. I have used different dialog boxes, ie. SdAskDestPath2, AskDestPath, etc... and by default, I am setting a network path unc like "\\server\share\folder". So it appears in the textbox or label but when I click the "Browse" or "Change" button (depends on dialog), I get this error message box that says, "Unable to browse the network. The request is not supported." So then I click OK and the browse window opens up. I pick the same shared path and click OK, no error and be on my way.

So the question is, how can I default the SelectDir or SelectDirEx function to use a UNC without giving me that error when I click the button?

I been trying to find the answer for weeks, please help
