I have had a version of this bug in *almost* every version of Aqua 
Tcl/Tk. It plays hell with my application. Fortunately there it seems to 
be solved in Tcl/Tk 8.4.16 (I suggest the ActiveState installer, but 
there is a bare binary and installing from source also works). If you 
want to use an older version for some reason, the *only* one I know of 
that works is 8.4.11. Everything I've tried in between has exhibited the 
problem of sometimes reporting bad mouse coordinates..
