I'm not sure where to report the bugs of the new DesktopX 3 beta, so here it is..
I'm not sure if it IS a bug however.
Here is the code sample.
Sub Object_OnLButtonDownEx(obj,x,y)
Obj.name="Thisiscool" & rnd
End Sub
Basically, if you run this code, it will rename any child object that was clicked to "Thisiscool" and string of random numbers.
Otherwise it's great experence.
