I have a frame which contains internal frame, when we right click on the internal the default system popup menu is seen. Moving the mouse to any corner(border) of the internal frame will change the default mouse pointer(cursor) to resize mouse pointer(cursor) & right clicking the mouse to show the popupmenu & pressing escape key or clicking some where on the internal frame so the popup is disappeared. the cursor remains to resize cursor where ever the mouse is moved on the frame or internal frame. This is incorrect

Step to reproduce
------------------
1) Run the attached program.
2) move the mouse to the corner of the internal frame ( border ). Observe that mouse pointer changes from default cursor to resize cursor.
3) Right click the mouse System popup is visible.
4) Press escape key or click some on the frame or internal frame. If mouse pointer changes to remains to resize cursor , then bug is reproduced.
