When a JTable has a popup menu and the right mouse button is pressed, held, and dragged to highlight various menu items (Motif-style popup menu behavior), corresponding JTable rows also become selected/deselected.

This problem is seen on Win NT and Solaris with JDK1.1.5 and swing-pre-1.0 release.


Steps to reproduce the same,
1. Run the Application.
2. Right Click on 'Verified by 5' cell - The menu pops up.
3. Keeping the key pressed, move the mouse over the popup menu.
4. The menu items are selected/deselected and so also the rows of the table.
5. The rows should not get selected/deselected when the menu is activated.


Sample Code is given below,
