Tad001 - I was able to duplicate the issue, and here is a work around:
- Shutdown the TFTP service by either using the services control panel applet, or the 'Stop Service' button in the TFTP configuration dialog.
- Close the dialog if it is visible.
- Right mouse click the TFTP server icon in the system tray, and select "Exit".
- Run the TFTP GUI application and change your TFTP Root folder.
- Start the TFTP service via the configuration dialog.
- Do a transfer now to verify the root location has indeed changed.
Thanks for finding this issue, and we will try to get is resolved as soon as we can.
