Ok, figured some of it out. In my LSP Sequencer directory there is a file called "tbmru" with no extension. It contains a list of filenames, so I moved that file out of the folder and opened LSP and the previous list was empty. But seems like that is kept backed up somewhere as it reappeared. So I just edited it with a text editor to delete all but the first file, and loaded it and only that file showed up. But again when I closed LSP the file repopulated with all the other sequences. I will keep playing with it, but not sure where else to look for this list. Went through the windows register, but nothing in there.
