Download Insight notifications no longer appear after update to 17.1

Hi.

 

Been using NIS2010 on W7 x64 on my home pc since its release and am very happy with it.

 

However, since automatic updating to 17.1, whenever I download an .exe file I no longer get the download insight notification in the bottom right corner.  It would always appear prior to the version update and I haven't changed any settings.  Also, my laptop (Vista x32) continues to show them after the update.

 

Any ideas as to why it no longer shows on my home pc?
