Hi,
I tried the same thing on your site today and it didnt hang the browser. I then proceeded and downloaded the latest version (even though it said 6.6., a lot of files were updated on 22nd december). When I now run the same example on my site it doesnt hang. So it means that the issue was addressed? Didnt see it in any news/announcements. Also i had previously sent a font issue when using custom sizes like 11pt, 13pt (the drop down didnt show size when i clicked on text which used this font size) and it also seems to be fixed now.
Thanks for that however a proper announcement and bug fix list would be helpful. I see a bug fix list in news and announcements but it doesnt tell which version (asp, .net or PHP) and also doesnt list my issues.
Thanks.
