Problem with pasting a copied line onto a selected text

Hi Actipro,

I ran into a problem performing copy-and-paste in Syntax Editor. 

Here are the steps to reproduce:

1. In any Syntax Editor (eg. SDI Code Editor - Inline of the Sample Browser).
2. Place caret at line 5 (without any selection).
3. Perform Copy (Ctrl+C). The whole line is placed into System Clipboard.
4. Go to Line 14, an empty line.
5. Perform Paste (Ctrl+V).
6. Expected/Observed: The clipboard text is pasted into line 14, along with its EndLine. This results in Line 14 and Line 15 being modified.
7. On Line 8, select a some text (eg. the word Generics).
8. Perform Paste (Ctrl+V).
9. Expected (similar to Visual Studio and other text editors): The clipboard text is pasted in replacement of the selected text (clipboard replaces the word Generics).
10. [Problem]Observed : The clipboard text is inserted in Line 8, the existing text in Line 8 is moved to Line 9 and the word Generics is removed.

Would you be able to fix this?

Thank you.

Regards,
