Dopus freezes after VPN connection severed

Once a week I connect to a Server share at work via VPN (OpenVPNConnect if it matters)
I copy a blank form to my desktop with Dopus access a resource over the VPN and fill out the form locally and copy the filled out form and a log file back to the file server resource.

If I do not point Dopus to a local folder before I sever the VPN connection Dopus freezes and I have to kill the process to get Dopus functional again.
Even if I ...point the lister to the 'Desktop' it seems to try to hold that connection.

Anyway it is not a big deal to me but thought I should report the application freeze.

Cheers

More a Windows issue than an Opus one. I think Explorer will do the same thing.
