    I'm not sure I have seen such a report. It is hard to know how to
    diagnose the problem. When you see the sluggishness, are you by chance
    working on a file that is in a Dropbox folder and you have automatic
    save set to a high frequency? That's just a random guess. We have seen
    some problems from users with both Windows and Dropbox.


Indeed the file is in a dropbox folder. But "Look&Feel->Document Handling->Backup documents every X minutes" is set to 5, which doesn't seem bery high frequency, and the problem persists even if I edit a copy of the document I placed in a non-dropbox folder.
If you open the Windows Task Manager and then start editing a document in LyX, does the Task Manager show either high CPU utilization or high disk utilization for anything?
