extjs4 - IE9 での extjs 4 テーマの問題、グリッドバーの色とボタンが変わらない

Question

次の sass コードがあり、コンパイルすると、Firefox と chrome ですべて正常に動作します。私が持っている唯一の問題は、Firefox や Chrome(Blue) と比較して、グリッドバーの色が無地の白である IE にあります。それに対する解決策はありますか。私はextjs4を使用しています。ここに変数のコードがあります

// This line changes the location of your images when creating UIs to be relative instead of within the ExtJS directory.
// You MUST set this to true/string value if you are creating new UIs + supporting legacy browsers.
// This only applies to new UIs. It does not apply to default component images (i.e. when changing $base-color)
// The value can either be true, in which case the image path will be "../images/"
// or a string, of where the path is
$relative-image-path-for-uis: true; // defaults to "../images/" when true

IEで見るとこんな感じ
