>I am creating VFP executables and attaching icons. I can create icons by modifying those given out by Microsoft, but the 'Thumbnail' of the icon, that which shows up on the taskbar, stays the same. Does anyone out there know how to modify the 'Thumbnails'?

You have to create a 16x16 (thumbnail) image and store it in the same .ICO file as the 32x32 (standard) icon. If you have VFP5, it came with IMAGEDIT.EXE.
