After testing the CamStudio procedure on another laptop, I was unable to duplicate starting BIAB in Windowed mode. Now I have one computer starting BIAB in windowed mode and one that always starts maximized and won't remember the last setting. Sorry I spoke too soon.

But at least it shows that it is possible for BIAB to remember it's last window size. Some setting other setting must have changed besides what CamStudio does.

Also, note that the shortcut properties don't affect the window state of BIAB whether they are changed from Normal to Minimized or Maximized.

Also, BIAB briefly flashes into fullscreen mode before going into its window.
