Description:
If the user copies a sql-query with more rows (more than 10 rows for example) from the clipboard, then the script window is at first not usable. The right scrollbar do not work too. But if the user makes a mouse click in the inner area of the scripting window and then press a key of the keyboard, then works the scrolbar now, and the user can use the scrollbar. After that is the scripting area usable and the user sees the inputing sql-query.
How to repeat:
1. Prepare a sql-query with the more than 10 rows with the help of a text editor and copy the text of the query to the clipboard (for example with CTRL+C).
2. Set the mouse cursor to the scripting window and copy the text of the query from the clipboard (for example with CTRL+V).
The scripting window will be not redrawed and isn't usable. The scrollbar on the right isn't usable too.
3. Set the mouse cursor to the scripting window and press any key on the keyboard.
The scrollbar is usable yet.
4. Move the scrollbar with the mouse ponter. The window will be redrawed yet and the user sees the inner area of the scripting window and can use the sql script.
