Thanks for the responses. Strangely the following script works:
import clr
import time
clr.AddReference("System.Windows.Forms")
from System.Windows.Forms import OpenFileDialog, DialogResult, Form
F = Form()
F.Show()
time.sleep(5)
This displays a form and then closes it when the script ends after five
seconds.
However simply swapping F.Show for OpenFileDialog().ShowDialog() causes
the script to hang.
I will check the suggestions made, but I wondered if this behavior with
the form gives anyone some additional clues.
Thanks, Andy
