Why no automatic refresh of file list?

[Beemer2]

I have reported this issue before but without it being resolved. In the downloaded file list, if I delete a file by alternate mouse click then selecting delete, the file is deleted but then the file list is displayed with many other files hidden. By that I mean the space they occupied is there but is blank. To see these files I have to select a different Newsbin tab then go back to the file list. Only then are all the downloaded files displayed. Using Windows F5 key to refresh does not make the files appear. Surely this is a Newsbin bug, as I have never seen this happen in any other program.
