XID collision, trouble ahead

[Yasha Karant]

I received the following warning when use Adobe acroread, X86-64 linux, 
installed within X86-64 SL6x using the SL6x Gnome and KDE (Gnome being 
the default GUI desktop) :

(acroread:12348): Gdk-WARNING **: XID collision, trouble ahead
Is this serious?  Other than a short freeze in the acroread GUI (would 
not accept any input), everything seems to be functioning.
