Thank you for contacting us.
Please, accept our apologies for the delayed reply.
Form the provided description I was not able to understand completely what is the exact scenario you have. What is the role of the RadAjaxManager in your scenario? May be when the first process finishes no postback occurs and for this reason the RadProgressArea does not disappear. How the second process monitoring is started?
I will need more details on the scenario you have in order to help you with this issue as quickly as possible. That is why, I would like to ask you for a simple running application which demonstrates your scenario and reproduces the problem. Please, also send me a list of simple steps to reproduce the problem. I will be glad to help you.
Looking forward to receiving your reply.
