Shapes move by themselves?

[athom45]

I am using Visio 2007 to create a floor plan.   My background drawing is an imported CAD drawing of the building architectural plan.

I arrange my furniture in a separate "Furniture" drawing.  I line up my furniture with the background drawing and it looks beautiful.  I save it.

The next time I open it I see the furniture has shifted slightly.  It is barely noticeable.  This happens every time I open and save the document, so that over time my furniture shfts significantly against the background drawing.

Can anyone tell me why this happens?

I don't know if it makes any difference, but the document resides on a shared drive with three different people accessing the document.  We all have Visio 2007.

I can't think of anything that would cause that.  Does the background update when you open the Visio file?  Perhaps the background is shifting?

Here's a simple test:  bring up the Size and position window (it's under the view menu).  Select a shape or two and note their coordinate positions.  Do same with background.  Now you have detailed reference positions.  This will at least pinpoint what's moving and by how much.

Thanks for the reply.  This is very puzzling, but has also shed some light on the cause.

I did as suggested.  I noted the reference points for a few shapes, saved, closed, re-opened.  The reference points do not change, the shapes don't move.  I do this a few times and all still looks good.  I close the file.

I go to my co-workers workstation and he opens the same drawing file from the network share.  Now the shapes are misaligned against the background on his workstation.  When I check the reference points for the background drawing and the furniture shapes they still match my original reference points!  He saves the file.

When I return to my workstation and open the file, the shapes now appear aligned relative to the background..

So the shapes are not actually moving, but they appear to have different positions relative to the background when opened on different workstations.  It appears as though we have all been "cleaning up" the drawing by realigning the shapes as they appear on our workstation, which is what causes the shapes to move.

So the real question is, why does the drawing appear different on two different machines?  We are both running Visio 2007 on Vista.

Are the printer settings the same on both workstations? Paper size, margins etc?

That's kinda funny, well, perhaps not for you.     Could have made an Abbot and Costello routine.

Couple other things in addition to what Paul asks:  a.) are the monitors the same, b.)  same resolution, c.) same drivers?  Or, what's different between the two computer stations?
