Build Identifier: I20100608-0911

The TableViewer doesn't scroll horizontalyl while dragging and moving a column in direction to the other invisible columns. This happens only on Windows (Max and Linux seems OK). 

Reproducible: Always

Steps to Reproduce:
Use a TableViewer in your application with a lot of columns (there must be some invisible ones) and try to drag and move a column in direction to the insivible ones. Normally, there should be an auto scrolling, but using Windows there is no one.

Snippet:

public static void main(String[] args) {
    final Display display = new Display();
    Shell shell = new Shell(display);
    shell.setBounds(10,10,200,200);
    shell.setLayout(new FillLayout());
    Tree tree = new Tree(shell, SWT.NONE);
    tree.setHeaderVisible(true);
    for (int i = 0; i < 20; i++) {
        TreeColumn column = new TreeColumn(tree, SWT.NONE);
        column.setText("col" + i);
        column.setWidth(50);
        column.setMoveable(true);
    }

    shell.open();
    while (!shell.isDisposed()) {
    	if (!display.readAndDispatch()) display.sleep();
    }
    display.dispose();
}

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

If the bug is still relevant please remove the stalebug whiteboard tag.
