eSearch buffer issue

Using AGS server 10.1 (recently installed yet still fixing issues) and FlexViewer 3.0, I found that the buffer function in eSearch is not working for me. The graphic never gets created and therefore nothing is then selected by it.

What might the issue be? I'm having issues with accessing the server directories (such as arcgisoutput)...are these used by the widget? If so then I know the problem but if it's not that then I'm unsure where else to look.

I'm not sure what other details you may need...

Thanks!
