One inch square box does not draw one inch.

Question

If I try to draw a square box in any size, illustator does not make it square.
For example, if I select the Rectangle Tool, click in the art space and set the rectangle to one inch by one inch, I get a box that is 1.0003 by 1.0003
Here is a screen shot of what I am getting.
This is also happening to any rectangle and circle.
Even if I hold down shift to keep the preportions lock, it still happens.
I have check and nothing is snapping or set to snap.
This is a major issue for me as I use illustator for creating dielines and those dielines need to be very accurate.

Jason,
It seems that something is seriously wrong, or they just fobbed you with an off measure version (the error seems to be far below any Stroke Weight, and Align to Pixel Grid should actually give a precise inch, or at least 0.01389 above or below it, depending on the positioning on the Artboard).
You may try the following (you may have tried/done some of them already, and 5) is less likely) and see whether it helps (the following is a general list of things you may try when the issue is not in a specific file; 3) and 4) are specifically aimed at possibly corrupt preferences):
1) Close down Illy and open again;
2) Restart the computer (you may do that up to 3 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool, and reinstall.
