When I search on a message and some of the ones that I have sent come up in the results, and I do a Select All to move them, Why do my own Sent messages get moved as well!!!

If they are in the Sent folder,
then they should either not show up in the results, or
be locked into that folder so that they cannot be moved, or
at least be given the ability to be replaced back into that folder so that I do not have to deselect them by hand out of every search result.

This is creating a file keeping mess as numerous msgs that I expect to be in the Sent folder cannot be found and thus there is no accurate log of what has been sent or not.

Additionally, if I do a search for 'me', it does not come up with anything remotely helpful to indicate which ones SHOULD have stayed into the Sent folder, and so you are creating a further mess with your lousy code.

This did work correctly some time ago, but during one of your recent updates, you released the locked Sent permissions and created this mess.

Please pay attention and fix it!!!
