vanishing cursor

[Eric S. Johansson]

every so often, something triggers a bug in Xwin which makes the cursor 
vanish but only over an Xwin window.  Only way to get back is to restart 
the X server (and windows).

another odd bug is that I noticed emacs tends to bleed through and pop 
up either ToolTips messages or menus even though a another (X or MS) 
window fully covers emacs.

thanks for any help that's available
