Thank you for these details.
We are still not able to reproduce the issue locally. Could you please, confirm that you are able reproduce this issue at all times? If yes, I want to offer a GoToMeeting
session. This way we will be able to debug the issue on your PC. As a prerequisite, you should download the sources of RadControls for WinForms
using your client account. I checked that your local time is GMT+01:00 while ours is GMT +02:00, so I would suggest that we hold the meeting at 10:30 AM your local time (11:30 AM our local time). Please, confirm whether this is suitable for you and I will arrange the meeting.
I am looking forward to your reply.
All the best,
the Telerik team
