Documentation for extended windows styles say : $WS_EX_LAYERED Creates a layered window. Note that this cannot be used for child windows.

But msdn say : Windows 8: The WS_EX_LAYERED style is supported for top-level windows and child windows. Previous Windows versions support WS_EX_LAYERED only for top-level windows.

_FileWriteFromArray appends Windows CRLF line endings to all lines, with no support for Unix/Linux LF endings. This either requires post-processing with external tools or even more hacky solutions. This seems like a vital enough omission to consider it a bug, as it could silently cause things to fail on many Linux servers, for example. Please consider adding a parameter to configure the line ending, or maybe only append an CRLF if an LF is not detected.
