Message ags_work_appln.sap when attempting to Configure System Monitoring

Hi, Solman experts,

When I attempt to select option Configure System Monitoring or Maintain Solution, I get a list of our solutions, when selecting the solution, I get the message "Do you want to open or save ags_work_appln.sap (816 bytes) from salmanserverhostname.

When selecting Open or Save and then Open nothing appears to happen.

Screen looks as below.

Any ideas?
