-// VZ: apparently some version of Windows send extra mouse move messages after
-// a mouse click. My tests under NT 4.0 and 95 didn't show it so I'm
-// tempted to think that it was just an effect of a poor mouse and so the
-// code to work around this is currently disabled - just define this as 1
-// to reenable it
+// [at least] some version of Windows send extra mouse move messages after
+// a mouse click or a key press - to temporarily fix this problem, set the
+// define below to 1
+//
+// a better solution should be found later...
