Thanks Thomas,
you found a new bug - of sorts.

To quickly fix this, locate the line in win32lib.ew that looks like this one
...

    vWindowClassStyle = {CS_HREDRAW, CS_VREDRAW }

and change it to ...

    vWindowClassStyle = {CS_HREDRAW, CS_VREDRAW, CS_DBLCLKS }

this will work fine now.

Alternatively, if you don't want to change the library code you can do this
in your program, before you create the first window...

    sequence x
    x = classDefaults(Window, {{CCwinstyle,{CS_HREDRAW, CS_VREDRAW,
CS_DBLCLKS }}} )

-----------
cheers,
