copy-paste not working in a standalone

[André Bisseret]

Bonjour,

Mac 10.6.8 ; Livecode 5.0.2

I have a standalone for an app. since 2011 with which all is OK.
Particularly, it allows copy-paste with command + C and command + V in any stack of the app.

Several times this morning, I tried building a new standalone for the same app.
But now, copy-paste does not work! (In fact, seems that it is only copy (with command +C) that does not work

What am I missing (or doing wrong)?

Thanks a lot for any help

Best regards from Grenoble

André
