[Plugin: WP-SynHighlight] Panel in tinyMCE shows #WPSynHighlight_dlg.WindowTitle

Hi. I tried a lot of syntax highlighters and WP-SynHighlight is the best one for me. Thank you for your great work! I love the GUI panel. o(∩∩)o

But there is a small problem. The title and labels on the pop-up panel in tinyMCE are all like this: {#WPSynHighlight_dlg.Language}, {#WPSynHighlight_dlg.Language}. I have the latest WP-SynHighlight installed.

I found these strange strings in tinymce/panel.php and tinymce/langs/en_dlg.js. But I don’t know much about PHP and JS and thus don’t know how to fix it.

Is there any problem with my web server or is it a bug of WP-SynHighlight?

Thank you!
