I created a spreadsheet that contain hyperlinks to web-sites the other day. When I try to click on them today I get a message that says "Unable to open http://........ Cannot locate the Internet server or proxy server." I double checked the address and if I click Edit Hyperlink, copy the address and paste it in my browser, the next time I click on the link, it works. But once I close the file and reopen it, it no longer works. Do you have any suggestions?? Thanks!
