修改历史标记选项无效？

[code399]

点击修改历史标记选项怎么不起作用？

It only works when no changes were made. e.g. after file loading:

notepad4/src/Notepad4.cpp

Lines 3921 to 3927 in 5bbf685

	case IDM_VIEW_CHANGE_HISTORY_MARKER:
	if (iChangeHistoryMarker != SC_CHANGE_HISTORY_DISABLED || !SciCall_CanUndo()) {
	iChangeHistoryMarker = (iChangeHistoryMarker == SC_CHANGE_HISTORY_DISABLED)? (SC_CHANGE_HISTORY_ENABLED | SC_CHANGE_HISTORY_MARKERS) : SC_CHANGE_HISTORY_DISABLED;
	UpdateBookmarkMarginWidth();
	SciCall_SetChangeHistory(iChangeHistoryMarker);
	}
	break;
