[Lazarus] LCL and DLLs, initializing the widget set safely?

[Phil Hess]

What widgetset are you testing? Calling Application.Initialize never worked before on Windows.

On Carbon, an LCL form in a .dylib was working as long as a year ago, but Windows would freeze when the DLL form is displayed.

Thanks.
