Win 7 Pro 32bit SP1 new installation.
When I open up Windows Explorer the file list is only about 60 mm wide. The Preview pane occupies the rest of the right hand panel. On my screen that is about 450 mm. So I drag it to about half way across where it is good for me. I go into Tools > Folder Options > View and Apply to all folders. This works and all the other folders have the right size preview pane. When I close Explorer and re-open it, the Preview Pane is occupying most of the screen again for all folders including the one I adjusted. I can turn off the Preview pane but I would rather have it on.
After a bit of research I got ShellFolderFix and then resized the Preview pane but it still does not remember the size.
Thanks for any assistance.
