Hello,

here is an updated version of my Zoom utility for Mathematica V6.0.1:

Load it in with Get and a Palette with one button is created. Then 

select a graphics and hit the button.

Zoom2D[g0_]:=Module[{g,g1,pp1,pp2},tt=g0;

If[!MatchQ[Head[g0],Graphics|GraphicsBox],CreateDialog[{TextCell["Zoom: 

No Input available."],DefaultButton[]}];Return[];

];

g=If[Head[g0]=!=Graphics,ReplaceAll[g0,{GraphicsBox->Graphics,LineBox->Line,FormBox[x1_,x2___]:>StringReplace[x1,"\""->""]}],g0];

g=g/.NCache[_,x_]:>x;

{pp1,pp2}=(PlotRange/.AbsoluteOptions[g])//Transpose;

g1=DynamicModule[{p1=pp1,p2=pp2,lp={0,0},aspect=1},Column[{LocatorPane[Dynamic[{p1,p2}],Show[{g,Graphics[{Opacity[0.1],Rectangle[Dynamic[p1],Dynamic[p2]]}]},ImageSize->Small]],EventHandler[Show[g,PlotRange:>Dynamic[Transpose[{p1,p2}]],Frame->True,ImageSize->Full,AspectRatio->Dynamic[aspect]],{"MouseClicked":>(lp=MousePosition["Graphics"])}],Dynamic[lp]

,Row[{TextCell["AspectRatio fixed: 

"],Checkbox[Dynamic[aspect],{Automatic,1}]}]},Center]];

CreateDocument[g1,WindowSize->{Small,All},WindowTitle->"Zoom-DH",WindowElements->{},WindowFrame->"Palette",BoxForm`ClosingSaveDialog->False];]



CreatePalette[Button["Zoom",Zoom2D[NotebookRead[SelectedNotebook[]]]],WindowTitle->""];
