In particular, the progress percentage specified to InbvUpdateProgressBar(), or the progress feedback made with InbvIndicateProgress() calls, is **relative** to the progress sub-range specified with a previous call to InbvSetProgressBarSubset() (by default, the range is 0...100%). This functionality is used e.g. when the number of progress steps is unknown prior, for example when loading drivers: in this case progress is made within a given percentage range. This bug has always been with us since 2010.
