When I ctl-F, the find dialog does not have the "results options" at the bottom. So I can't tell it to append to a search results window, etc. It used to have it. It disappeared a couple days ago and hasn't come back. I had a couple odd failures around the time it disappeared because I opened some huge file and ran out of memory or something. Not sure, but I remember some popup stack window appearing.
The Find in Files tab still has results options.
