What happens with Xojo 2023r1.1 with old project files?

An image worth thousand words:

NO, the greyed entries ARE ONLINE.

They are only no more “openable”…

Hover with the mouse over the lines with the question mark and you will see a tooltip “The file is missing”. Maybe you moved the files to another folder or an external drive is not connected…

Apparently, I was wrong: I checked some of them, and they are off line !

Memory failed: I forgot I opened so many project form external HD/SSD.

BTW: I displayed only a small part of the greyed recent files. Adding a flag to say Off Line is a good thing / I love it.

You can also right-click those items to remove them from the recents list.
