 4             this.debug("Removing Flash functions hooks (this should only run in IE and should prevent memory leaks)");
 5             for (var c in a) {
 6                 try {
 7                     if (typeof(a[c]) === "function") {
 8                         a[c] = null

 4             this.debug("Removing Flash functions hooks (this should only run in IE and should prevent memory leaks)");
 5             for (var h in f) {
 6                 try {
 7                     if (typeof(f[h]) === "function" && h[0] >= 'A' && h[0] <= 'Z') {
 8                         f[h] = null;
 9                     }
