My PC (WinXP Pro) went through daylight savings change last night. Now uVision3 A51 behaves incorrectly. When I build a project, files that have not changed are built. Before this problem, if I built a project only those files than changed (or their dependencies) were assembled and linked. Now some files are assembled and some not and I can find no reason why. I have rebooted, copied all files, deleted all obj, .lst, etc. I have looked at the windows file info and scanned the registry but I cannot find a reason why uvision3 thinks some files should always be built.
Any ideas?
