12 * TODO:
13 * -Check ranges when changing field-focus.
14 * -Check all notifications/behavior.
15 * -Optimization: include lpipsi in IPADDRESS_INFO.
16 * -CurrentFocus: field that has focus at moment of processing.
17 * -connect Rect32 rcClient.
18 * -handle right and left arrows correctly. Boring.
19 * -split GotoNextField in CheckField and GotoNextField.
20 * -check ipaddress.cpp for missing features.
21 * -refresh: draw '.' instead of setpixel.
22 * -handle VK_ESCAPE.
