Two different PCs.  Both nearly identical except one is a laptop, the other a mini tower on the net at a desk. Both running the exact same version and SP0.0 for SW 2010. Both OS identical.  Both updated weekly. Both nearly identical Nvidia cards. Both machines edit the exact same part opening it one PC at a time.

Desktop will not creat fastener feature "Mounting Boss".

Laptop works just fine.

Created boss feature on laptop and once opened in desktop we see this Icon in the FT:

A little man with a half an iPod in his ear.  Can't find this anywhere in help.

Can't open, nor edit the Boss1 in desktop.

Go back to laptop and the icon is:

Just as it should be.  In the laptop, we can edit the feature all day long.

Tried Rx, nothing.

Tried reboot, nothing

Tried forum, waiting with fingers crossed.

thanks
