 Description

I just experienced an exception thrown by the vertical scrollbar opening a worksheet (collection was modified; enumeration operation may not execute);

I cannot reproduce so may be some threading issue...

 

 

Errore message (got it again)

System.InvalidOperationException: L'insieme è stato modificato. L'operazione di enumerazione potrebbe non essere eseguita.

Ever see that "collection was modified; enumeration operation may not execute" error? Yeah, I just got it again! For me, it usually happens when I'm messing with lists in parallel. Closing and restarting the app usually fixes it. Anyone else find a permanent solution? It's almost as frustrating as losing in Basket Random .
