It is ALWAYS helpful to have video along with the series of steps to create
bugs to show the problem.  Programmers need this to see what the bug is and
then to ensure that it is fixed.  So far we have been able to reproduce the
bugs you have found so will not need a specific project yet.
P.S. You are GOOD AT FINDING PROBLEMS !! and that is very helpful so please
continue to report.

I have always wondered if changing the Cache size makes any difference and
I think you have proven that it really does.

Not sure if this is a performance issue, per se.  I just do not have the
expertise to say for sure.
