After the v3 update any Field/Control object that displays an image regardless of its hierarchy on a layout can not be selected or dragged by clicking on the object. You can drag around the object(s) to select but you can not select or move directly.
Change the Field/Control to any other field type and you can then select it.

In Windows XP, it does not seem to make a difference what kind of object is on top. I can't select the objects underneath by clicking them directly.
I just did a few more tests.
If I put a rectangle that is transparent and that has no line width on top of some fields. If I click once, the rectangle is selected, but if I click on one of the fields and drag, that field is selected and I can drag it...
A rectangle formatted so that it is initially invisible can be almost impossible (very frustrating) to select in layout mode
Dragging over the item will select it, but then the usual, right click to choose options such as button etc, causes more frustration as the right click deselects the rectangle again.
Here is a sample file with 3 comparible objects, all invisible,
all with a mouse over effectI removed the mouse over effect since that entailed making them buttons etc.
2 can be selected and manipulated perfectly fine, the rectangle cannot.
Tested on Windows 7
