Hi Stefan:

I made the following modification to upload.js and UploadButton.js to solve this problem and it seems to be working with no IE8 issues existing till now so far.

Upload.js:

    _onEnabled : function( evt ) {
      qx.ui.core.Widget.flushGlobalQueues();

      // change the enable statement by modifying the "disabled" attribute to solve this bug: 
      // https://bugs.eclipse.org/bugs/show_bug.cgi?id=299741 by tingel christian.
      // The IE8 issue seems to be inexistent here.
      if( evt.getValue() ) {
        //this._uploadField._button._input.style.height
        //  = this._uploadField.getHeight();
        this._uploadField._button._input.style.disabled = "false";        
      } else {
        //this._uploadField._button._input.style.height = "0px";
          this._uploadField._button._input.style.disabled = "true";
      }
    },


UploadButton.js:
_createInputFileTag : function(elem)
{
...

      input.style.zIndex    = "100";
//      input.style.cursor    = "pointer";
      input.style.filter    = "alpha(opacity=0)";

...
}

Tested under IE6/IE8/Firefox3.6.2/Chrome4.1.249.1036

The upload widget is obsolete and will be removed in the future. Use the new FileUpload widget or the FileDialog implementation from the incubator instead.
