Sorry, I made some mistake.
It is NOT a bug of IE, but a bug of the wordpress program.
I can give a workaround here:
Search for the followin line from wp-admin/inline-uploading.php:
h = h.replace(new RegExp(‘ (class|title|width|height|id|onclick|onmousedown)=([^\'”][^ ]*)( |/|>)’, ‘g’), ‘ $1=”$2″$3’); // Enclose attribs in quotes
and replace it with this one:
h = h.replace(new RegExp(‘ (class|title|width|height|id|onclick|onmousedown)=([^\'”][^ ]*)(?=( |/|>))’, ‘g’), ‘ $1=”$2″‘); // Enclose attribs in quotes
To Kmp:
This problem is caused by a bug in the javascript engin in IE. Try firefox, and you will find the size of your picture will be set correctly.
