RE: [PROTEL EDA USERS]: Moving problems

Ok, let's beat that dead horse, only once more...
Dear Abd ul-Rahman Lomax,
either I misunderstood one or more of the recent statements or there *is* a
bug that I did't recognize yet (or both). I know that (when moving
selections) the bounding box may not represent the extent of the selection
due to hidden primitives, turned off layers and so on. 

But does the cursor snap to this bounding box? I didn't ever realize. And I
can't remember a discussion here about this issue. There are weeks I don't
have the time to read every posting. (would be great to have a searchable
archive............again)

I never care about this bounding box (when moving). I personally wouldn't
consider it a bug, (if the cursor does not snap on it, what is my question
now)  because with the bounding box one can recognize also that there are
perhaps hidden primitives or even hidden layers (from a previous selection)
that are also moved. Please correct me if I'm wrong.
