Downloading images through System Console

I am working with the Arria 10 GX eval board and have created a dashboard in System Console to allow me to control my design. My dashboard has a combo box to allow me to select from a list of sof files and a button to allow me to download the selected image. The following is the code attached to the button:

proc btnDownloadClick { } {

global dash

global my_device

set filename [file join output_files [dashboard_get_property $dash cboImage selectedItem]]

foreach possible_device [ get_service_paths device ] {

if { [ regexp 10AT115 $possible_device ] } {

set my_device $possible_device

}

}

device_download_sof $my_device $filename

}

When I first open System Console this code works as expected. I can then use System Console to interact with my design. If I then attempt to download a new image, I get the following error message. I have to exit and restart System Console before I can download a new image.

=== error message follows ===
