I’m a new user, my first Support topic was closed early. I would appreciate if it was reopened.
Could it be that I accidentally hit Solution? (I suppose it’s only the author of the question, i.e. me, that can choose a Solution). I read the thread on my tablet (touchscreen) so I guess it’s not impossible some virtual button was hit while swapping / scrolling. If that was the case I think the site designer might want to look at double-validating this action (“Do you really want to …” pop-up)
