Hi John,
Could you please send me (andrew.medvedev@alternetsoft.com) cut-down version of your project where the problem can be seen as we could not reproduce it?
regards,
Andrew

The project is too complicated. Anyway, we found the problem if the tooltiptext in IListMember is set to null. So solved on our side.


Thank you
