I also thought that next event to launch the browser was executed while the previous browser process was still closing.
However it might just be a problem specifying the browser.
On line 1 and 2 using the Browser method the browser can be specified by the process name "iexplore" etc.

On line 3 using the Browsers Object item property a browser can be specified via built-in constant, by the process name or by index within the collection.

If myBrowser = a constant like btIExplorer it won't work on those first 2 lines.
