I am having a problem using Internet Explorer 8 (IE8) to open mailto links with long messages.
After the user clicks on the link, IE changes to an about:blank page
I also tried with the solution CBono posted but I coudn't make it work either. I found that when you directly paste the mailto URL in the browser it has no problem no matter how long the string is. So, I implemented something like this:
Send Email
As CBono mentioned, if you want this to be dynamic, you just need to pass the mailto string as parameter to the function and assing it to the sMailto variable.
Hope this helps.
