write protected portable installation: error on exit

[emeekers]

I created a portable version of NPP with a selection of plugins. This portable version should be write protected to avoid users to change the configuration. When a user who has no access to the folder exits the application, he gets the following error.
Error message:
CSVQuery.dll just crashed in
notify(SCNotification *notification) :
notification -> nmhdr.code == 1009
notification -> nmhdr.hwndFrom == 00000000001403EA
notification -> nmhdr.idFrom == 0

A user having access to the folder does not get this message.
