I upgraded my site's DLL to 2.4.0. I have a standard diagram with multiple "blocks" in it, and depending on the users selection, I move this blocks to / from visible layers.
On diagrams with a resonable amount of content on the visible layer, I get "Index was outside the bounds of the array." when saving. If I change the DLL back to 2.3.0, the "problem" goes away.
Also, if the diagram only has a few blocks on the visible layer, DLL 2.4.0 works fine.
Has there been a change in saving between 2.3.0 and 2.4.0?
