■試した改善方法
１．selenium バージョンアップ(0.8.3 -> 0.9.2)
http://release.openqa.org/selenium-remote-control/0.9.2/selenium-remote-control-0.9.2-dist.zip

解決せず。

２．ブラウザ指定を変更
id:otao さんの記事を発見。
http://d.hatena.ne.jp/otao/20070206

ー set BROWSER="*iexplore"
＋ set BROWSER="*iehta"

TestRunnerのエラー内容が変わった。

IEでスクリプトエラーがポップアップされた
ライン: 1075
文字: 9
エラー: 書き込みできません。
コード: 0
URL: file://C\DOCUME~1\ユーザー名\LOCALS~1
    \Temp\customProfileDir881171\core\TestRunner.hta

 このページのスクリプトを実行し続けますか？

   はい(Y) いいえ(N)

はい、いいえ。どちらを押下しても動かず。。

うーむ。
