If I put a timed loop inside a structure (stacked or flat sequence, for loop, while loop, event, or even another timed loop) then expand the inner timed loop horizontally within the existing bounds of the structure, the structure grows, even though there's already enough space to accommodate the timed loop's larger size.
Some details...
1. This only happens horizontally, not vertically. If I expand the timed loop in both directions simultaneously, the structure only grows in the horizontal direction.
2. If I disable Auto Grow for the timed loop, the problem goes away, but then of course the timed loop doesn't auto grow to accomodate stuff inside it- unless that stuff is another timed loop.
3. Disabling Auto Grow for the containing structure does NOT make the problem go away.
4. This behavior includes multiple nestings; if a timed loop is nested with a case structure within another case structure, both case structures expand.
5. Other structures, terminals and wires external to the enclosing structure are moved if their midpoints are beyond the edge of the timed loop being dragged. This happens even if the timed loop isn't enclosed by any structure. Again, this only happens horizontally, not vertically.
I'm using LabVIEW 8.5.
