Silent Mode feature turn on by itself NIS2010 version 17.6.0.32.

Can some one assist.......

 

Lately, I noticed strange issues with NIS2010 version 17.6.0.32.

 

Silent Mode feature turn on by itself.  I had configured for silent mode to turn on but not for that particular program.

 

Strangely, everytime I exe the program, NIS2010 system tray ICON turned "grey" even when the program was not configured in the User-Specified Programs.

 

I cannot manually turn off silent mode it turned off only after closing the program.

I am puzzled as how to handle this.

 

Thank you for your help.
