I have several documents with multiple layers, and by multiple I mean up to 100 or so. They are all very simple layers, most times with one word. The files are for printing to a laser engraver which has a standard shape on one layer, and the rest of the layers are single words that are centered to the shape layer. When I print, the shape layer is "visible" but not printable or selectable. Just one text layer is visible, printable, and selectable (for the purposes of printing "center/center" to the center of the wood piece being engraved). So, I'm only printing one layer at a time.
Here's the issue: The object manager obviously has a multitude of layers, all of them invisible except for the layer to be actually printed, and the shape layer visible just for visual reference. Many times, when I change a layer to invisible from visible (or vice versa), or change a layer from printable to non-printable (or vice versa), or make a layer selectable to non-selectable (or vice versa), the object manager will jump to another layer entirely, marking that layer with the change I made to the original layer (while also making the desired change to the original layer). So, it's doing its job, and then some. If I change layer 27 to "visible", for example, object manager will also jump to layer 54 and make the same change. I have to change layer 54 back to "invisible" and scroll back to layer 27 to resume work. I'm lucky, I guess, that at least it goes right to the unintended layer when it does this jumping around, but I still have to find my original layer to resume work. It happens with every change, so I'm spending a lot of time jumping all over the layer list in object manager. I can't seem to come up with a pattern for this behaviour, it seems the layers with the unintended changes are randomly chosen.
Sorry about the length of this question, but it's a little difficult to explain. I guess this might open up the discussion of "how many layers is too many layers", but these layers have extremely limited simple content.
A quick test shows that this problem is present in CorelDRAW X8, X7, X5, and X3.
Very good find, Eskimo!
Sorry to start the thread and disappear, but your description is spot on.
It's OK. Life happens!
Thinking about how you use this, I would also comment that, instead of using layers to accomplish this, an alternative might be to have them all on one layer, but individually hide/show objects to control what prints.
It only recently came to my attention that "individually hidden" objects are excluded from printing. I find that non-intuitive, considering that hidden layers DO print.
I'll have to make a test file using that method. The first problem that leaps to mind is that I use grouping and powerclips a fair amount (on some of the multi layer files), and when ungrouped I would have a single layer with multiple "free range" objects that I would then have to regroup by picking them again. At least when there are multiple layers, the "free range" ungrouped items would be contained somewhat.
And yes, hidden layers printing is counter-intuitive, in every sense.
