11 * TODO:
12 * Using DPA to store the item ptr would be good.
13 * -check custom draw
14 uHotItem
15 * use separate routine to get item text/image.
16 *
17 * FIXMEs (for personal use)
18 Expand: -ctlmacro expands twice ->toggle.
19 -DblClick: ctlmacro.exe's NM_DBLCLK seems to go wrong (returns FALSE).
20 -treehelper: stack corruption makes big window.
