1. Start with a large directory of JPEG files (at least a few hundred
pictures, say about 400 or 500 from a normal photo shoot). These must have
a few files that are not rotated yet, but which have the proper Exif tags.
2. Select all 500 files with Irvanview "File->Thumbnails->Options->Select
All" and then press "File->JPEG Lossless Operations->Lossless Rotation With
Selected Files->Auto Rotate (according to Exif orientation, if
available)->Optimize JPG File->Apply original Exif date/time to new
file->Keep all APP markers (default)".
3. Every time I do this, only the first hundred or two hundred pictures are
rotated; the rest seem to not be touched. If I select a hundred pictures at
a time (slow at best in the Irfanview thumbnail viewer), then, over
successive operations, I can manage to auto-rotate the entire set.
This looks/smells/tastes either like user error (but where?) or a
previously unknown bug in Irfanview.
Can another confirm that Irfanview batch lossless autorotation by Exif tags
fails to run on all selected files for large numbers of files?

Have you emailed Irfan about this? In my experience, he's very
responsive to questions and bug reports (as much as his schedule allows
him to be, anyway).

I have seen bugs similar to this with programs that use the MFC
CFileDialog class.

Don't know. I have replaced 4.1 with 4.2. Give it a try.

That is not a virus. Just an alert that the executable is 'compressed'. My
opinion is that trendmicro should not have panicked in this case.

No. What it is saying is that this particular file is possibly
infected because it has characteristics that are suspicious.
It has yet to be determined by Trend Micro if it actually is a
virus.

Great -- more FUD regarding a great piece of software (IrfanView).

Then bozo why did you EXPLICITLY state the following?

^^^^^^^^^^^^^
Irfanview freeware bug? Batch JPEG lossless autorotation. Large directory failure consistent 
Linear Mode
