Screen refresh triggers document change

Dear all,

In my script I have set up this notification:

Notification (Constants.FA_Note_PostActiveDocChange, true);  

I have now noticed that this is also triggered (executing the Note function) in the following situation:

• Script is active in a dialgogue, which stays open (is palette). It remembers the 'current' location in the user document to be able to restore it after changes in the document by the script.
• I switch to the document and do some text editing. Normally I do not need a screen refresh and can then proceed to the palette of the script.
• If I do a screen refresh (CTRL +l) the notification triggers and the script restores the last 'current location'. In most cases this is the start of the document.

My questions are:

• Is a sceen referesh really a 'change in the document' and thus the behaviour correct?
• Or is this my mis-interpetation of FA_Note_PostActiveDocChange ?
• Or am I the victim of an unsharp defintion of FA_Note_PostActiveDocChange ?

Thanks for any thoughts about this.
