Avoid application becoming unresponsive on download

Question

Hi

• I have an application which downloads a file from a network location and then displays that files information.

• It uses WebClient.DownloadFile to achieve this.

• The problem is, when the user clicks a button to start the download, the application becomes unresponsive until the file has downloaded. This gives the impression the application may have hung.

• I would like to seek ideas which would avoid this scenario. Though my solution will need to be 'as quick and cheap as possible' I would be interested in hearing about custom loaders that have been built, or some sort of loading symbol / progress bar / sand time clock thingy : )

Thanks for reading.
