About a week ago Solid Works 2013 stared using 12.50% of the processor even when no models or drawings were open. It appears this don’t start happing until I print a PDF drawing file. The only way to release the 12.50% of the processor usage it to shut Solid Works down and restart it. I have seen another program use 12.50% of the processor usage Adobe Acrobat 9 Standard.  I think it is really Adobe causing this but it is reporting it is Solid Works. 2013, Has anyone seen this or know how to make it release the processor usage without rebooting Solid Works? Thank You, Sam
