Writer is slow opening documents

If LibreOffice is running, and no documents are open, there is a 5-8 second delay when opening an existing document (double-click on document in Finder). Very annoying.

If LO is closed, there is minimal delay.

If another document is already open and displayed on the screen, there is no delay. But if I close that document, then double-click on another, there is a 5-8 second delay before it opens.

This is ongoing for a long time. NeoOffice has no delay at all.

v4.3 OS X, and many previous versions…
