7 * - I am not sure about the default values for the Min, Max, Pos
8 * (in the UPDOWN_INFO the fields: MinVal, MaxVal, CurVal)
9 * - I think I do not handle correctly the WS_BORDER style.
10 * (Should be fixed. <ekohl@abo.rhein-zeitung.de>)
13 * Not much. The following have not been tested at all:
15 * - listbox as buddy window
18 * - UDS_ALIGNLEFT, ~UDS_WRAP
19 * (tested - they work)
20 * - integers with thousand separators.
21 * (fixed bugs. <noel@macadamian.com>)
23 * Even though the above list seems rather large, the control seems to
24 * behave very well so I am confident it does work in most (all) of the
27 * I do not like the arrows yet, I'll work more on them later on.
