Dear Mr. Camarena,
sorry for coming back late to your question.
we are not sure if this case is still current for you but we wanted to make sure that
your request is covered.
regarding your question:
we have just checked the behavior and were trying to reproduce the situation
but couldn't make it fault.
have you checked the behavior in different browsers?
maybe a browser add in is blocking the operation somehow.
one thing you could do would be to restart your IIS and reset the MSMQ:
otherwise you could create a support request for our software support team if you need further assistance.
anyhow: updating to the latest service pack is always advisable if your using an on premises installation.
Mit freundlichen Grüßen / With best regards,
Software Support Specialist Team BLUE EMEA
