The application is Illumina's GenomeStudio (its older predecessor BeadStudio,
also have this behavior lately). There is no public demos, unfortunately.

If it helps, here is a screenshot: 

The new ArgumentOutOfRange Exception seems to be thrown by the periodic
progress bar update. (the small highlighted foreground window on the bottom
right) - or something to do with screen update, as it is thrown "periodically"
without any user input, during certain applications. Oh, I just realised the
textual content of the log panel (the one that says "Log" at the bottom back)
has completely disappear with 2.8.x. The content of the Log panel is also being
continually updated during normal operation. 

I am not sure of when the regression happened - but I am 100% sure that during
late 2.4.x the the same procedure/progress bar can run to completion without
the exception. (at the moment it is throwing an exception about 6 times per
time and the progress bar is per 24-sample so we are taking about a hundred
exception pop-ups which requires acknowledgement to continue).

I'll give this a try...
