Possible Causes
Internet Explorer 8 cannot use the Vector Markup Language (VML) to draw graphs because its bottom-layer dynamic graph library VGX.dll is deregistered.
Procedure
Run the following command as the Administrator user on the local client to register VGX.dll:
regsvr32 "%CommonProgramFiles%\microsoft shared\vgx\vgx.dll"
Close Internet Explorer and open it again to log in to the eSight.
