I just wonder whether any of you have received memory leaking complaints? We are using the 2.4.1 paramquery in a desktop application and we discovered that there are memory leakings. When we replaced code with earlier versions of paramquery such as 2.1.0, there's no memory leaking. We found that the memory leaking typically is triggered by mouse-move in cells (or maybe column heading), and then memory just keeps going up slowly. If you are not aware of such issue, please let me know, I might need to spend some time to present you a concrete bug case.
