/_layouts/myfolder/myjs.js - and the script loads and runs in Firefox (even in different instances and with different plugins) but not in IE 10, nor in Chrome.
The script is just this:
I've tried regular old js script links, and I've also tried the delayed loading, like this:
<SharePoint:ScriptLink ID="myScriptLink" runat="server" Name="/_layouts/mylib/myscript.js" LoadAfterUI="true" OnDemand="false"/>
What could cause this?
