All I did was add a column to a custom bin view (named Standard Use)...

And... everthing disappeared.   Plus,... Ther are no Selected columns to choose from for display.

What is the deal?   Any way to recover without rebuilding the Bin View?

See attache pic

Have you done a system restart?

yep... first thing I tried before I posted...

OK... so, I decided to try and rebuild the bin...

And... it was rebuilt... then, I changed windows... went back to the bin by clicking mouse over the bin window... and, the custom went blank again... and, the window with column option also went blank.

Anyone every had this problem?

OK.... this is only preliminary... but, as best I can tell...

This problem seems to be indirectly or directly related to the Script Window isse with MC5.

Apparently... the Comments column can actually disappear from the list... until this re-established the bin will be unstable and can be lost and not recovered or not successfully retained after it is rebuilt.

The simple solution is to go to the Script tab a simply put a temp comment into the area intended for comment in the Script window.  The Comments column will now appear and (so far - knock on wood) it will remain visible and the custom bin view remains stable.

Why the "Comments" colunm has a tendancy to simply disappear is something that appears to be a bug... which may have something to do with the overall problems some have been experiencing with this portion of the Project Bin.
