Hi,

this has been reported twice in the forum and is a regression.

I tried a regression test but it fails because in March there was first a
commit that prevented to start the program at all, and after that was fixed,
this error was present ,,,

Steps to reproduce (requires a little knowledge of french):

Install the app, then choose the example and then select "Operations" from the
menu, select some row, double click and try to use the date picker: the error
message box appears

The only thing I know for sure is that it worked before

user32: Use UNICODE_STRING for passing window classes internally.

I`m not 100% sure (because regressiontest fails)  if this is the cause of the
bug but I added you (Jacek) anyway the bugreport, hope you don`t mind ;)
