Cannot save settings with Networked Desktop

Hi,

I have just started using SOAP UI and seem to be having trouble as my Desktop & other user files are shared from a network drive. In particular, I get the following error when trying to save settings:

java.io.FileNotFoundException: \\SERVERNAME\Desktop$\soapui-settings.xml (Access is denied)

My actual desktop is at:

\\SERVERNAME\Desktop$\paulthom

Any thoughts on how to tell soapUI to look in the right place?

Thanks for your time,
Paul Thompson
