Good morning Chris
The user may think that they are copying from the active layer to the cosmetic layer - but they haven't, they have pasted into the active layer.
And the term "active layer" is a bit odd as all layers are active.
Or do you mean the "editable layer"?
You can select and copy from any layer - points, lines, polygons - but when you paste, you paste into the editable layer - whichever that is set to. It is a common error by users. But a polygon would never turn into a point object!!
Moreover, now you have pointed out the process, there is no need to copy and paste at all (let's eliminate the error arising in the first place).
If you select the polygon object (the planning application) and then Browse >Selection it will become
Query X. You can add Query X to the Map and turn off the original layer. Does that fit?

Thanks Nick
There are mostly blank rows but I think a couple have data which would definitely suggest user error. My colleague has come back with a subsequent question...
..."ask if there is any way that copying and pasting lines or polygons between an active layer and the cosmetic layer could result in point data being created on the live layer?
I have discovered that a similar situation appears to exist on a different layer (Development Control) which has polygons drawn on it. I have investigated one particular example where two separate applications have been recorded relating to the same site. The original application is shown (correctly) as a polygon, but the subsequent application appears as a point. I have seen the map created for the second application for the response to the planning application and that clearly shows the polygon. The person doing this will have either:
Copied and pasted the original polygon in the Development Control Layer and then amended the details behind the new version to reflect the latest application. Then they will have copied and pasted the polygon into the cosmetic layer and switched off the Dev Control layer in order to drawn a plan with no nearby applications showing, or,
- Copied and pasted the original application polygon into the cosmetic layer and switched off the Dev Control layer in order to drawn a plan with no nearby applications showing. Then turned on Dev Control layer and copied and pasted the polygon from the cosmetic layer into the dev control layer to create a new record with the same outline and updated the info behind it.
Could either (or both) of these processes have resulted in Mapinfo creating a point record?"
Cheers
Chris

Chris,
No log files are created in the flat files Pro uses. MapInfo creates temp files when a layer is originally edited until the layer is saved. Then they're gone. If the data is held in some sort of spatial server then maybe that will create time/date stamps for individual records.
I don't think in 25 years I've come across Pro randomly creating data so my gut instinct would be user error.
You could lock down the editing permissions for that layer or the folder it sits in to try and minimise the potential for this or even trap who is doing it.
Do the points have blank rows in the browser? i.e. no attribute data. Possibly been added by mistake, i.e. insert symbol is selected rather insert polyline. The user could be then adding them without realising? maybe.
Regards
Nick

Hi all
Is there a way to see when events, e.g. map features like points being created, occur for a particular Mapinfo layer? I ask because a user has queried why random points seem to be appearing in a polyline layer of his unexpectedly. If we could pinpoint when these additions are occurring we might be able to investigate. Is there a log file stored for a layer which would show actions similar to the way the mapbasic window does?
Thanks
Chris
