If you have an anchored item that consists of a Group, when you convert your file using Q2ID, the Anchored item will no longer be Anchored.
In the example below, the QuarkXPress file has an Anchored Inline Graphic that consists of three circles grouped together. As one adds or deletes characters the three circles move along with the text.
When the file is converted using Q2ID, the Group is retained, but is no longer Anchored. In the example, the Group was moved outside of the text box to illustrate the fact that the group of circles is no longer Anchored.
