11 * - I think I do not handle correctly the WS_BORDER style.
12 * (Should be fixed. <ekohl@abo.rhein-zeitung.de>)
15 * Not much. The following have not been tested at all:
17 * - listbox as buddy window
20 * - UDS_ALIGNLEFT, ~UDS_WRAP
21 * (tested - they work)
22 * - integers with thousand separators.
