When you create a new document from template, and this template is a "plantilla de cómic europeo" with the following layers: * Page0 (the selected layer) * Mask clone-outline * Ink * Color * Sketch * Mask * Background After the page has been created, trying to paint directly over it with the mouse, the mouse is stopped when the button is pressed and nothing happens. There is no information about why it can't paint there.
This is because the page in question has a group layer at the top. Selecting the sketch, ink and color layers allows you to paint. This is not a bug, unless the bug is supossed to be that grouplayers don't tell you you cannot paint on them.
I would rather set it to wish; we should show an on-canvas popup if it's not possible to paint on the layer.
Also... didn;t we at one point open templates with a paint layer pre-selected?
Which layer is selected is a matter of which layer was selected when the file was saved. It might be a good idea to go through all templates and see if they don't have a non-paintable layer selected.
