lines disappearing , help

[phillyd023]

When I am drawing a line all of the other lines on other layers disappear as I draw the new line. when I release the mouse button they reappear. how do I stop them from all disappearing?

Hold up .......... I had a picture layer at the top tht I made transparent for tracing. When that layer is visible I have the problem, if I make the layer visible the problem persists.

Question revision ........ how do I make the lines stop disappearing while the picture layer is visible?

Drag the image layer under the vector layers.
