In Things I created a link to a to-do with Hookmark and inserted that link into an Excel spreadsheet. When I click on that link in Excel, Things is activated, but I get the same error as in 6248:
The link itself looks like this:
https://hookmark.net/hm/things//show?id=UiBuR7eu5TaDX3v1bWRpV
I even tried it with a triple slash before the “open” keyword but still get the same error.
The Hook-link works fine from any other app (e.g. DEVONthink) but only returns the error when clicked in Excel. It makes no difference if I tell Hookmark to copy as “normal” or as “universal” link.
