When I select a layer in the TImageEnView and use CTRL+C then CTRL+V to copy and paste a copy of the selected layer, I see two issues:

1. On a paste, the LayerSelectionChange event occurs. When pasting an ellipse or rectangle with no fill color, the CurrentLayer's FillColor property value at that moment in that event is something other than the copied layer's fill color. Instead of none, it might be red or some other color. The pasted object is correct. I use the LayerSelectionChange to update some controls on my form, and it is displaying something that is not true of the pasted layer. If I switch to another layer and back again, then it is correct. This only happens on a copy/paste.

2. The TImageEnLayerMView does not update to show the pasted layer until I do something to that layer, like resize it or move it. If I paste multiple times, none show up until I do at least one thing to any of the newly pasted layers then they all show up. The TImageEnLayerMView also updates if I start a new layer other than pasting the copied layer. I figure I need to force a refresh of the MView, but not sure where that should go to not needlessly update the MView. In other words, I guess I need to know if a paste just occurred. I feel like I'm missing some sort of event handler for this to refresh the MView, just have not figured out what it is.

Thank you for the detailed report, Eric,
