Mathematica; NotebookEvaluate inside CreateDialog

[ChristinaJ]

The following creates a button window to select a notebook to run. When a button is pressed Mathematica finds the notebook but cannot evaluate it. The following error occurs
Could not process unknown packet "1"

CreateDialog[
  DialogNotebook[{Column[{TextCell[
       Row[{Style["I would like to ...", FontWeight -> Bold]}], 
       "Text"], 
      Row[{Button["run 1", 
         NotebookEvaluate[
          "/../file1.nb"]],
        Button["run 2", 
         NotebookEvaluate[
          "/../file2.nb"]],
        Button["run 3", 
         NotebookEvaluate[
          "/../file3.nb"]]}], Button["Done", DialogReturn[]]}]}]];

This occurs under Mathematica 8 on all platforms.

Any help greatly appreciated,
Christina

Solved here thanks to http://mathematica.stackexchange.com/. The issue was with Button and not CreateDialog.
