This is not a bug, but it bugs me! In my M51 map file, some files are shown on the included command line as residing in ".\filename.obj" and others as just "filename.obj", even though they are all in the same place and uV2 shows them as being in the same place. The linker seems to be just echoing what the uV2 project builder is telling it, but what does it mean? Also, I type in all my .c and .h filenames in lower case, but uV2 will sometimes show the name.ext in all caps, just the extensions in caps, or just the name in all caps. I wonder why. I am using Windows NT 4.0, svc pak 6a, and am using networked file shares. Thanks in advance for any clues. George
