Yes (search the issue tracker, this has been reported recently –maybe
it was you?–)

Attach onclick handlers to your links to call History.newItem and
Event.preventDefault(). That's what GWT's Hyperlink do to workaround
this IE "quirk".
To attach the onclick, you could loop through the
Document.get().getElementsByTagName("a") (before attaching your GWT
widgets) and call DOM.setEventListener and DOM.sinkEvents.
However, I'd rather expose the History.newItem method as a global JS
function through JSNI and attach the onclick handlers in the host page
HTML: <a href="#tab1" onclick="GWT_History_newItem('tab1'); return
false;">
Another option is to just have placeholders in your HTML host page and
"inject" GWT Hyperlinks in there (RootPanel.get("tab1link").add(new
Hyperlink("Tab 1", "tab1"))).
...if only there were a SimpleHyperlink widget with a static wrap()
method to wrap an <A HREF> and set the EventListener automatically...
