My database has fields that contain web addresses I want to open in the default browser. Then I created an icon and set it as a single button to open the url associated with the record the user was on. All this has worked for me for years and years until this morning when none of my links work. Each icon with a script I click on brings up the default browser's home page.
For kicks, I just added a button to open up www.filemaker.com.
Open URL [With dialog: Off; "www.filemaker.com"]
When clicked it too brings me to the default browser's home page instead of the www.filemaker.com.
