Hi Dave.
When I examine it so far,
Problem is shown remarkably with Windows-XP and 2003.
Former patch was the thing to indicate the problem place clearly.
Then, a problem is complex though it could be cleared to a certain extent.
First of all I showed the need of the modification.

It is thought to make the most of it as a material to proceed in a solution of a problem.
However,
Application to our wxWindows worries whether I should wait for the result.
any idea?
When patch is applied, a solution is done.
