Re: [Xsltforms-support] I18N: Bug and proposed fix for Windows Asian IME with xf:input DOMActivate

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Please check r503 for Windows Asian IME support.

I currently have problems for testing with IE7 and IE8 while it seems to 
be OK with IE6.

Thanks!
