Code Issues Releases Activity

Avoid hourglass mouse pointer when a tooltip for menu item is shown.

Browse Source 
src/w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
 mouse movement events if the menu bar is active.  This avoids
 producing a busy "hour-glass" cursor by Windows if the mouse
 pointer is positioned over a tooltip shown for some menu item.

movement events might send these events to the tooltip
frame, if the user happens to move the mouse pointer over
the tooltip. But since we don't process events for
tooltip frames, this causes Windows to present a
hourglass cursor, which is ugly and unexpected. So don't
enable tracking mouse events in this case; they will be
restarted when the menu pops down. (Confusingly, the
menubar_active member of f->output_data.w32, tested
above, is only set when a menu was popped up _not_ from
the frame's menu bar, but via x-popup-menu.) */
