In some situations my clients are receiving the message the system is busy with other operations switch to or retry buttons will apppear along with cancel but inactive button. Then they need to logoff and login again are cancel the application and need to start again. This will apper very frequently. Kindly advice me whether it is a network problem or server problem or application problem.
