Is it possible that the ProgressBar has problems with big values?

My application uses the Progress bar to indicate the progress made during
loading and parsing binary files.

ProgressBar.Maximum is set to the file size - i'm using the
BinaryReader.BaseStream.Length property for that. 

For updating the value i'm using something like:
ProgressBar.Value = (int) BinaryReader.BaseStream.Position;

With small files (< 8 MB) it works like expected (like in .NET) -> the
ProgressBar continually grows.
With files > 8 MB and < 16 MB -> the ProgressBar first grows continually to the
half and then disappears
With files > 16 MB -> the ProgressBar first grows continually to the half, then
disappears for some time and then begins to begin growing from start.
..

In .NET it works like expected but the mono ProgressBar does not seem to be
able to handle Values greater than approximately 8M
