laurent no im sure that vsync is off, besides I have a crt with 100hz, so it should be on 100 then, not 62.

}QuoteI had to click in the bar (the bar at the bottom in windows, don't know what its called) to make it visable.
Can you show us a minimal and complete code which reproduces this behaviour?
QuoteThe point is that you can only load textures into OpenGL when the window is already opened
That's not true. There's a dummy window created at program startup to provide a valid OpenGL context.
It's no more true with the latest sources (global initialization + DLL can cause some issues), but if you can still use SFML graphics classes without worrying about creating a window.
In case you just want to use custom OpenGL calls, you can call sf::Window::ForceContextInit() (static function) to force the creation of the OpenGL context before you create any window.
QuoteThe second created window (my main window) starts minimalised
You really mean minimalized (ie. hidden in the process bar), or just "not maximized" ?
QuoteIt would be nice if we could hide a window from start, and unhide it when needed. This way the window is initialised and can be showed very quickly
Why would you need to create a hidden window ? Just create it when you need to show it.
QuoteError handling. SFML automatically outputs to the console when an error occured. Thats nice, but what if I output printf() to a file and want to use my own error handling? It would be nice if we could use something like 'geterror' and it would return the latest generated error. And eventually 'geterrno' which would return a error code which can be identified and dealt with.
SFML doesn't output to the console. It outputs to the standard error stream, which you can easily redirect to whatever you want.
I think providing some error codes would be useless, SFML functions just need to tell if they succeed or fail.

, would be wonderfull to see it improved even more .
