Thanks for your information.
1. I tried it again. Recording is not working for the frameset on the left side and the right side (entire site)
2. I can work around it temporarily by using non-frameset version.
3. I can't send to you the HTML page because it is the company policy. :(
On Pages.g.cs , it shows the following code:
private Manager _manager;
private static int s_frameTimeout = 5000;
public Pages(Manager manager)
_manager = manager;
public static int WaitForFramesTimeout
