I just installed SW2015 and I have a script error on every startup. 

    Line: 201

    Char: 5

    Error: Object Expected

    Code: 0

    URL: http://www.solidworks.com/includes/js/panes/swpane.main.js?v=F40E7966

I checked the js file and found that line 201 calls SearchResultsRemove().  I clicked on SW Help\Search\SolidworksHelp and did a simple search.  Then I exited SW.

Next startup - no js error.  But subsequent startups brought the error back.
