Well, what about a case where it's a modal dialog-- the most straightforward
modal dialog you can imagine, with one button, one disabled static text
item, and one editable text item?  From the behavior of the text as I
click and type, I can see that the selection point/range is being properly
selected, but the feedback to the user has two problems:
1.  The blinking caret never appears.  It never even makes one blink.
2.  When I select a range of text with the mouse, the text becomes
    inverted (white on black),as normal.  However, if I click the mouse down in
    the text again, the text is not re-inverted back to normal.  If I
    select a smaller range within the original larger range, the smaller
    range is inverted back to normal (black on white);  the formerly
    selected text to the left and right of the new selection stays
    inverted, even though it isn't selected.
Is there something I'm not doing right?  The modal in question has no
filter proc, no user items, nothing.
