ok i found where this was happening.
it was in upload.asp
<input style="font-family: MS Sans Serif; font-size: 9pt; vertical-align: top;" type="file" name="test" size="40" maxlength="50" />
changed it to
<input style="font-family: MS Sans Serif; font-size: 9pt; vertical-align: top;" type="file" name="test" size="30" maxlength="50" />
now the browse button for this file input is visible
