The operating system is warning that the application has been downloaded from an "untrusted" site so double-clicking doesn't start the application. One way to work around the problem is to right-click (CTRL-click) on the application and select the <i>Open</i> option from the resulting menu. This pops up another window that allows the user to "open" (run) the application.<div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>dave riley</div><div><br></div><div><br><div><div>On Oct 30, 2013, at 1:38 PM, Sandy Graham <<a href="mailto:sandyg@gvtc.com">sandyg@gvtc.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><meta http-equiv="Content-Type" content="text/html; charset=us-ascii"><meta name="Generator" content="Microsoft Word 14 (filtered medium)"><base href="x-msg://577/"><style><!--
