ZOrder Behavior Changed in Excel 2007?
 

Argh! Form controls now *always* appear on top of shape/drawing
objects. What's up with that? Prior versions of Excel allows you to
send Form controls behind shape objects by right clicking on them and
choosing "Order-Send to back".

Ok, so you're probably asking "why would you ever want your form
controls to be hidden behind a drawing object?". Good question. I
developed an Excel application that dynamically displays floating
"help windows" made from the text box shape objects on top of my input
form. Actually, these pseudo help windows are comprised of several
shape objects because I went so far as to give them title bars (with
an "X" close button) among other features.

Now in Excel 2007, all the form controls are displaying on top of my
help windows.

Is this a bug or a feature?
