Rich Edit Object and Scrolling

I'm making a chat client lately. It's all going well. I've missed one thing on the way. When a message comes to you and there is more text than can fit without a scrollbar the text doesn't scroll down. I fixed this with scroll down action whenever a message comes. It all goes well but now there is a bug which I'm having problems with tackling. I have my chatbox, it's got some text in it and i click somewhere so the cursor is somewhere in the middle, not at the end of text. Now when a message arrives or a new line is added the text is added at the place of cursor. I was thinking of moving the cursor down by using the Go to line action and I put number of lines from scrolling as the value. But it doesn't seem to work. So does anyone have any solution. I would like quite a detailed solution. Most appreciated would be solution similar to how it's done in Gwerdy Chat.

Make it the rich edit read only?

Doesn't change anything... You can still set teh focus on.

yep, you need to set the char. position to the amount of characters in the RTF object before you apply the text :)

Also use the Rich Edit action Block->Unselect Block

How do you make it so it will scroll down automaticly?

I need help here. This is the only bug I need to fix before I release it.

The best I can come up with is:
[events]
*On message
+GetLineCount( "Rich Edit Object" )-1 is entirely visible
-(Rich Edit) : Deselect block
-(Rich Edit) : Go to character number GetNChars( "Rich Edit Object" )
-(Rich Edit) : Set string to message
*On message
+[NEGATE] GetLineCount( "Rich Edit Object" )-1 is entirely visible
-(Counter) : Set Counter to GetFirstLine( "Rich Edit Object" )
-(Rich Edit) : Go to character number GetNChars( "Rich Edit Object" )
-(Rich Edit) : Set string to message
-(Rich Edit) : Go to line number value( "Counter" )[/events]
The only improvement I can think of is to buffer the new text until you scroll down, so as to not mess up selections and suchlike.
