I can't select objects on my page.

Serif Software > DrawPlus
Applies to: All DrawPlus versions.

If you are working with a multi-layer drawing, then DrawPlus only allows you to select an object on the currently selected layer (by default). If you have accidentally or deliberately clicked on another layer in your drawing, then objects from other layers can no longer be selected.

Solution 1: In the Layers tab, select the layer on which the "target" object is stored. You'll then be able to select the object.

- or -

Solution 2: Allow selection (and editing) across all layers. On the Layers tab, click  Edit All Layers. You'll then be able to select any object across layers; the object's layer will be selected automatically.
