Dialog Box for un-connected links
 

Does anyone have any suggestions on dialog box for un-connected links?
My worksheet contains one or more links, which cannot be reloaded the
connection, once I click and edit the link, I find the status for the source
file - OK. I get no idea why excel pop up the dialog box for un-connected
links.
Does anyone have any suggestions on how to disable this dialog box?
Thanks in advance for any suggestions
