This issue is already fixed in Q3, and you should not experience similar problems with the latest version. Could you please check whether your GAC is clean from old versions of our controls? I am attaching a sample project referencing version Q3 and there is no undesired behavior. If you still experience problems, open a support ticket and send us a sample project, accompanied by instructions on how to reproduce the issue.
If we could be of your further assistance, do not hesitate to contact us.
