Issue working with two browsers.

1) Iím invoking two browser by setting the option: Agent.SetOption (OPT_VERIFY_UNIQUE, FALSE)
2) This works fine.
3) In one scenario, I need to shuffle between the browsers.
4) Problem is with the HTML link which there under a folder.
5) Silk is recognizing the folder correctly, while the HTML links are not.
NOTE: If I have only one browser, then the script works perfectly.

Another problem is, some time it works and some time it doesnít.
Iím currently using Classic agent.

Any help in this regard is highly appreciated.
