Transparent graphics are converted as ordinary graphics. Count Score to Total for questions is not carried across. All scores count to the total score, but in Perception, you can have different outcomes to a question all with zero score. These characters are also illegal inside a selection question item, hotspot description and inside a text match answer. If these characters are found in any of the mentioned places then they will be replaced with a space character.
Graphics can change slightly on exporting.
In multiple response questions the score if not selected is not exported. When exporting text questions, the size of the text entry box is not set to the same size necessarily as in Question Mark for Windows. The width is set as sensibly as the software can, but the height is always set to one row. You can easily manually adjust this later if required. Export is usually to plain text format.
