Hi, I have, today, installed Win 7 on a new computer. I have been using XP until now. I have googled and searched through the forum for an answer to this problem but can't find anything. Either I am the only one that has it, or I am the only one that it bothers Scenario: I have a folder with 200 audio files of various formats. I want to select only the .OGG files whose filenames start with "A". On XP: I would sort by filename, select all the "A" files, re-sort by file type, using CTRL and the mouse, I would then deselect non-OGG files. When I try this on Win 7 my selections are cleared when I re-sort. Is there a setting somewhere that I need to change? Thanks in advance.
