about problem #1: you are right, the query will ignore the current column order. I will have a look into that.
The second problem sounds strange to me. I have not experienced a similar behaviour yet. There may be some "forbidden" characters in the query result that lead to a database mixup. Could you give me some more information, eg. set the log dicom communication option in the ini file to 1 and query your conquest server again and then send me the communication.log file or relevant parts of it to my e-mail address?
