Total Commander

I'm not entirely sure how I went about it, but I was deleting some folders/files on a USB drive which required Administrative rights, and then I moved them to a background window.

I think that I selected several files again to delete (which were already scheduled to be deleted) and deleted them, again it required admin rights and I moved it to the background.

Suddenly I got lots of "TCMADMIN.EXE" popups/msgbox-es informing me something went wrong -- see machine translation below -- and I had to close quite a lot of these (50 or so) which was quite tedious - if it would be possible to have a "close all" or "don't show again for this session" option that would have been nice. I don't think I can replicate it, so not sure how to test it if it is added.

machine translation so may not be accurate wrote:TCMADMIN.EXE - Delayed writes failed
Could not save all data for file [path]; data has been lost. This error may be caused by the device being removed or the media being write-protected.
