With the old symbology when a layer is transparent, if an object is selected it becomes yellow and is also transparent. With the new symbology the selected object is not transparent.

I disagree that this is a bug. In fact I think the bug is as it behave in the old symbology.
In the old symbology a 100% transparent object is "unselectable" in the canvas, as the transparency is applied also to the selection color. This for me is wrong/not useful. There is/was a ticket about this before the new symbology was introduced.
I would like to ear from Martin and others about this.

In Arcmap 9.3 a selected object remain transparent and with the same color of an unselected object only the outline is highlighted.
I think that it should be transparent, let's assume that I want to edit a layer and I need to have it transparent so that I can see the layers under it. Then I want to cut 1 object in 2, I select the object that I want to cut with the tool "Split features" (I selected it because I want to cut only that object), then i start to cut that object but I just can't see what is under the selected object.

Good news, I didn't even realized that now in trunk (maybe also in 1.6) you can set the transparency level of the selection color. You can do it in both the general options and in the project properties. When you choose the selection color you have also a "alpha channel" spinner.
This way, in the new symbology, you can see transparent as you want a selection of a 100% transparent geometry.
I believe that this solves your problem. Reopen if necessary.
