Oh, for something so relatively simple, it sure can be. Trying to make thumbnails of the docks I posted for download (forgot to add those). Using the thumbnail maker that comes with Instant Scenery. . .make sure the screen is filled with the green background and that the sample item in positioned in the screen ahead of you. . .check. . .and. . .check. Click "start". . .Error: Screen is not completely green. Position aircraft so that the entire FS screen is green and no other windows are open. Ya know what, my screen can't get any greener and if I zoom into the sample object any more than I already am the stupid thing disappears. Grrrr.:isadizzy:
