query builder diagram missing

[jmustac]

I created some queries using the diagram builder, but when i later opened the query the diagram was missing. the query text detail was still there but not the diagram. The DESIGN file is still there.
It doesn't happen all the time, just to a few of my queries. Is there any way to recover the diagram - i don't want to loose that detail.
