Moving object between tabs results in very low resolution?

Question

Hello,
I'm using Illustrator CS5
When I move an object to a new tab(drag and drop), the end reult is very low resolution/distorted image?

You are welcome, 1-2-3.
That alignment is the default for kinds of documents normally used for web and devices where it may be an advantage to work in whole pixels only. It is possible to change the setting for such documents.
What happens is that (part of) the artwork is moved to be contained within whole pixels, by the least possible amount. This also happens during creation so that the Anchor Points/whatever that you place are adapted, unless you place them at whole pixel positions, in other words small, maybe unnoticeable, corrections of what you do.
When you drag and drop, you basically just throw it into a new, normally off grid, position, and the parts of the artwork may be moved differently.
You may keep the undistorted shape even with Align to Pixel Grid ticked if you copy from the source document and then use Paste in Front/Place/Back in the receiving document.  You can also move it by whole pixels in either/both directions.
In any case, you may ask yourself whether you want (the individual parts of) the artwork to be contained within whole pixels, or more freely created. In the latter case, you should have Align to Pixel Grid unticked before you even start.
