Many, many thanks to you, 600, my hero
!
Please have a look at the two attachments, both have been made a few minutes ago.
And now, let's be serious. In a former life I have been Software Customer Support Manager at Hewlett-Packard France, and as such I'm stunned.
First, I consider that in such a product having two different actions with the same name (one of which does nothing, if I am not mistaken), i.e ambiguous action names, is a serious design fault.
Second, for four days there have been no reactions of any kind from the Playmaker staff, for which I have no words. "Disappointed" doesn't even apply.
Extremely sorry about all this.
Problem solved. Sort of.
