When I refresh my grid, it often collapses my outline to one level and all my work positions are lost. 

It comes up regularly because:

1) Changing format (eg fill color) sometimes doesn't show up in grid even though it's set to auto update
2) Link dragged into InfoQube sometimes comes in blank.

I've never logged occurrences but I'd guess it happens maybe 10-20% of the times I refresh.

This has been going on for a long time and I've just been living with it.  I know you won't be able to reproduce it or it would have been caught and fixed already but I'm bringing it up on the off chance you encounter it some time.
