Bran, Abdulrahman,

After reading your replies, some of my confusion has been dispelled. I agree
with you that if the mechanical layer set-up is greyed out, that there are
primitives on that layer. I only have two mechanical layers with nothing on
them. These are indeed selectable.

Back to my display problem. I have used the mechanical layers to create
drawings. For instance, one layer is the drawing template, another is text
with board specifications, others are titles with page numbers and so on.
When I go into preview, I combine the layers that I need to generate the
desired drawing. In preview, I have no problem getting the data to appear.
However, in the PCB edit mode, I cannot get every layer to display at once.
If I could, I would get everything that I have placed on every layer. I do
have all mechanical layers visible in the mechanical layers setup dialog. In
the design/options dialog I set use all layers. Now even though all the
layers do not display, if I scan with the mouse, an area known to have a
primitive I will see it pop up in the status display. I can then click the
mouse and edit its properties normally. When I close the properties box, the
primitive displays. When I hit view/refresh, it disappears. This board is a
simple 2 layer board. Layers directly associated with the board always show.
(top bottom, silkscreen ....)

I'm using sp6 on a win2k box.

Thanks for your help.

Ken, Abd-ulRahman,
        The description of the issue does not make a lot of sense to me.

        I note that if I have any primitives on a mechanical layer, the
layer name in the mechanical layer set-up is greyed out. I have always
interpreted this as the layer is in use and cannot be disabled. When a layer
name is not greyed, then there are no primitives on that layer and it can be
disabled or unchecked.

        Possibly Ken has mechanical layers color set to the same color as
his background making them essential invisible? This would not let them be
seen visually in the display but they would still be visible in a preview
print. Other then this, I don't know!

Weird. The checkbox is greyed if primitives exist.
What version Protel? 99SE? SP6?

The reported behavior is not normal for SP6.

What is the setting for the mech layers involved in Design/Options/Layers?
The reported behavior would occur if those layers were not enabled there,
except for the greying of the title, so I suspect that Mr. Henrich may have
erred about that, or he does not have SP6, or his installation is trashed
and he needs a reinstall.
