CreateWindowEx

[Gavin-Williams]

CreateWindowEx is returning a zero handle with the following output...

An unhandled exception of type 'System.InvalidOperationException'
Failed to create window class. Error: 1401

// error 1401 / 0x579 ERROR_INVALID_MENU_HANDLE

I'm passing default as the menu handle. I don't see a problem with that, it's what I've been using.

Update:
OK :
0.2.63
0.2.104
NOT WORKING:
0.2.138
0.2.158

I tried replacing default with GetWindowSafeHandle() but no luck

private static SafeHandle GetWindowSafeHandle()
    {
        return null;
    }

Also tried null, which it accepts, but still Error 1401.

I don't know what you mean by replacing default with GetWindowSafeHandle which just returns null. That doesn't sound like a change at all. And where did you make this change?
I'm not familiar with this particular API. If you can provide a compilable repro case (following the issue template we created) I can probably help further.

It looks like #760 probably regressed this by passing in -1 for hMenu instead of 0. I'll look more into this.
