Sergey,

that's a very good question !

Answering it, forced me to reproduce the error,

and I found only one very specific situation

(which I mostly use :-(

that can cause the error.

So after extensive testing I found the problem:

On opening my application, I open all the documents that where open when

the application last closed. And above that, I open all the documents on

the exact position where the were when the application closed.

Now if the first file to be automatically opened is a MDI-child with a

syn-editor, the caret problem occures in MDI-childs with either a

SynEditor or MDI-childs with a RVE.

By setting the caret behavior in syn-editor different:

SynEditor.AlwaysShowCaret:=false;

the problems in all other MDI-childs are gone ;-)

For me it stays very weird that a caret setting of

another component than RVE,

in another MDI-child

can affect the behaviour of the caret in RVE,

which is also in another MDI-child ??????

thanks for the help Sergey,

and if you've an explanantion,

well I'm still curious.
