I'm using jquery text editor jqte to allow users to edit content of some text areas. Whenever I add large text to the editor the browser hangs for a while then after few seconds (sometimes 1 minute) it comes back to live again then it hangs again when you are scrolling or editing. I mean with the browser hangs is that you can't do anything to the page, you can't click any buttons or even scroll down or up in the page. I tried to put some large text in their online demo and this behavior happens. Is it a bug or just there is some parameter tuning that could solve the issue ?
Note: I didn't put any code snippets because using this editor is quite simple and the behavior happens even on their online demo
