apache/php view pop-up from .NET dll
I am running Apache 2.3.16 with PHP 5.3.9.  I also have a third party .NET dll that I want to use.  I can successfully load the dll using PHP's DOTNET object, but I am having a problem when I call one of the object's methods.  This is the error message I get:
>Source: System.Windows.Forms Description: Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

So apparently there is some message or error being generated in the dll that is causing a pop-up box.  The problem is that I cannot see that pop-up to know what to do about it.  I understand that I am on the client side, and this pop-up is generated on the server, but I still need to know what it is.

Here is what I have tried so far:

 - On the Apache service, check "Allow service to interact with desktop"
 - Contacting the developer of the dll to see if they know what error might be popping up
 - Used the same dll in a simple Windows application to see if I could get an error

None of these approaches has yielded anything.  Is there anything else I can try?
