Base layer showing through

Thanks, Walt. The properties of all layers are set to hide items on the base layer, but the learner needs to get to the menu, so I can't prevent clicking on the base. 

And it doesn't feel like the 'last layer to show is on top' because when layer A is displaying and the learner clicks the menu, the contents of layer A stay on top, and the base layer graphics come up BEHIND it. If the learner clicks the menu again, the menu and the graphics from the base layer disappear and layer A remains.

BUT I realized that I've had this problem before...about a year ago and actually you replied to my post at that time! ;-) So I looked back, and here is how that conversation ended....

"Regarding the bug I mentioned earlier where hidden base layer objects appear on slide layers when a Slide Master layer is also open, I'll keep you posted on our progress."

My solution at that time was to place a white box behind all the objects on each layer which covered the objects on the base layer. As I said at that time, that solution won't always work, and my current project is a good example....'Michael' extends down to the bottom of the slide under a semi-transparent bar so it can't be hidden. I guess my solution is to change the design of the screen, but I'm hoping someone on staff can give us an update on this bug?

Thanks for your help, Walt!
