Uses IE browser to load a HTML page requires java plug-in 1.3.1, then visite another page requires java plug-in 1.4, a popup dialog appears to warn that plug-in can not attach a running VM. At the moment, dismiss the dialog box and close the browser, browser crashs.

Also, if you visite HTML page requires java plug-in 1.4 first, then switch to a page requires java plug-in 1.3.1, browser crashs.
