'Browse' button in HTML form not working in IE 7 or 8 (ietester)

Question

I have a really straight forward image upload form in a website of mine. For some reason, when I load up ieTester and use IE 8 or IE7, the 'Browse' button to locate the file has no text on it, and it also doesn't open a file selection dialogue.

Does anybody know why this might be? Could it be because I'm using IE Tester?

Here's the code for my form:

<form action="edit-profile.php" method="post" enctype="multipart/form-data">
    <input name="file" id="file" type="file" />
    <input type="hidden" name="uploaded" value="true" />
    <input type="submit" value="Upload" />
</form>

Thanks in advance for any help.

This appears to be a bug in the current version of IETester/DebugBar. It has been reported, although not yet acknowledged or dealt with.
