Are there any known changes in the ecma script engine between IDM 3.6 and 3.6.1?

Scripts that ran without any problems on 32-bit IDM 3.6 doesn't on 64-bit 3.6.1...

One example:
/* */
var myString = String("An example string");
var myStrLen=getLength(myString);
function getLenght(str)
var strLen=str.length();
return strLen;
/* */

gives TypeError: length is not a function.

Another problem I have is that that I can't create a new LDAPConnection object (Novell LDAP api) with a default socket time out.
No such constructor... Worse is that the setSocketTimeOut method isn't recognized...

Best regards,
