Hello,

I tried this, but what happens is that even after rv.Format is executed, and

the Screencursor is normal again, the contents of the RichViewEdit keeps

showing the old contents for several seconds, until the new contents is

displayed. This document contains a lot of large images, so I guess that rv

needs quite some time to really display them after formatting?

Load and format are very fast, just after that I have the delay, for which I

want to keep the mouse cursor "busy", so that users don't click other things

and wonder why nothing happens. During the delay time, the program does not

react to anything.

Regards,

Holger
