When I'm editing nodes in a polyline using the shape tool, I frequently want to combine the edited polyline with another existing polyline. So with polyline 1 selected, I hold shift key down and select polyline 2, I can then combine the two lines using Ctrl+L. However the act of selecting the 2nd polyline sometimes causes CorelDraw to crash - any ideas why this is?
This doesn't happen in a simple diagram with a few lines, but does happen in complex diagrams and can be replicated once it's started. It doesn't happen if the polyline are selected using the "pick tool", only when using the "shape tool".
I'm using CorelDraw X7, Windows8, but have also experienced this in previous versions.
What causes this problem??
