Unfortunately we don't. Again we tried to reproduce the problem in different scenarios but to no avail. I am afraid that without having a better view over your exact scenario and logic we cannot be of much help. Please try isolating the problem - you could start by removing all controls that are not necessary e.g. they are not using in the sequence of steps needed to reproduce the problem. Once you have a project that can be run locally and reproduces the error, just send it to us in a support ticket and we will check it right away.
