Qt Creator Editor is -very- sluggish

Hello.

Using Qt Creator to work on a real project with realistic number of files of realistic size, it becomes clear that the editor is very sluggish. So sluggish that its almost unbearable..one makes typing mistakes because the editor hast reacted yet to what one typed and one types again etc.

One of the most compelling reasons for using Qt Creator instead of say Momentics is that its a leaner more focused tool. Shouldnt be that Momentics (itself very sluggish) is significantly more responsive than Qt Creator

Hope this is something that can be improved upon.

Thanks in Advance
