Ajaxで質問です。

lightboxという画像を別窓でグラフィカルに表示させるJSのツールを使っておりますが、

http://openstratus.com/21/lightboxjs2

FireFoxで、開いた別窓に記載のある文字やリンクが選択できないようになってしまっております。
原因は分かりますでしょうか?


※ちなみにv2.0です。

ポイント60pt

FireFoxで、開いた別窓に記載のある文字やリンクが選択できないようになってしまっております。

というのは、画像の下に表示されるキャプションのことでしょうか?

それと、選択というのは、マウスで範囲選択できるかどうかの意味でとりましたがあっていますか?

Lightboxの公式ページの別窓はfirefoxではふつうにキャプションを洗濯できるようになっています。

差し支えなければ、不具合の発生しているURLか該当ソースを貼ってもらってもいいですか?

問題ございません。

URLは開発中のため、お見せすることが出来ませんが、メインのJSのソースを貼りたいと思います。
