I would like to set a minimum width and height on my split panes so that, when added or resized, they will never be a tiny square etc.

However, when I do this, on dragging the panes around, I occasionally get an ArgumentException with message "Width/Height must be non-negative". Oddly, it doesn't happen all the time. Other times, weird stuff happens - like the panels get cut off.

Anyone else seen anything like this?
