I've put together a snazzy Excel 2000/NT4 spreadsheet for computing lateral pressures on a sheet pile wall due to a strip load surcharge. It's snazzy in that I've used ActiveX controls that allow the user to change various parameters in the problem by means of scroll bars and thus simultaneously viewing such changes. That is, you move the scroll bar and at the same time (no waiting until you click off the scroll bar, unlike using a Form scroll bar), for instance, the distance between the strip load and the wall changes on a neat graphic.

That's not the strange part.

The strange part is this: each time I do a print preview, one of my text boxes is "nudged" a bit. I've never seen anything like this. I've got the text oriented vertically, if that matters. What on earth is going on? Is my computer possessed? (Probably...) This is sick!
