Yes indeed, Arrow size 0 induces the problem.
That's also why it helped to reinsert the contents to a pristine new file. Out of the box the Arrow size is 2.5, Tick size 0. When adjusting the Drawing Preferences I didn't bother to set Arrow size to 0 as it is enough if Tick size is more than 0 to activate tick.
So it's easy to avoid the problem, now that we know about it, but the problem will stick forever to that particular drawing.
A weird thing also is that when you click anywhere in the screen to ask for "Properties" it will always say "Dimension" on layer "Dimensions". As if that angular dimension is omnipresent, everywhere.

Maybe LordofBikes can enlighten us.
