I have a frame, which contains textarea , menus & a button. Clicking on the button. The menus on the menubar are removed & added to the popup menu of the textarea. I add some characters to the textarea, so that i can see both the scrollbar( enter some 15 to 20 lines ). I select few characters from the first line of the textarea. And right on the selected character so the popup menu is visible. Once the popup menu is visible. I click on the down arrow of the vertical scrollbar. I cam see the windows native standard popup menu(cut , copy & other menus). But i see that vertical scrollbar tumb moves towards the down arrow button. This is incorrect. but still the windows native standarad popup menu. I press ESCAPE key so that popup menu disappears. After that i drag the vertical scrollbar tumb towards the up arrow button. I see some painting is not happening on textarea. When you tag horizontal scrollbar tumb then painting in not happening properly on textarea as well as on vertical scrollbar.
