Thanks, in fact in the wx Installer there is also an option to suppress 
the installation of this files - but the name of this checkbox sounds so 
harmless, that I'd never expect it to have such serious consequences.
Why is this checkbox ON in the installer by default when it is not 
necessary for successful use of wx?

And I'd still like to understand the reason why win32ui apps at all can 
do such strange things like magic automatic pressing of buttons, when 
this .manifest  is active. (This caused some serious trouble here the 
first time, because this win32 tool did some real business transactions 
as OK-buttons were pressed automatically repeatedly until I could 
shutdown the app in the taskmanager..)
