Why is Key F10 unfocussing my program?

[Squarefox]

Hello,

I'm using an Irrlicht-FPS-camera in my program (runs in a window). If I press 'F10' the programm is unfocussed and I can freely move the mouse-cursor.
If I click somewhere in the programm-window, the programm is focussed again and the mouse-cursor is binded to the FPS-camera again.
The problem occurs wether I'm using 'F10' in the eventmanager or not. The operating system is Windows 7 x64.

Greetings,
Squarefox

Just tried it (also Windows 7 64 Bit .. but IIRC it's the same on my old WinXP-32 System). Same behaviour as with the "ALT" key. Program does completely freeze, after re-focusing the window my program takes all physics steps since the time it was frozen (so it takes a little time until it runs smooth again)

That's because F10 activates Microsoft Windows' menu bar options (exists since Windows 95) and Irrlicht (as of 1.7.2) didn't prevent it from being activated. If you hit up or down after activating it you'll get a simple window manager drop-down menu (minimize, close, etc.).

I recommend avoiding the use of those keys.

Seems to be fixed in svn trunk, probably won't be changed anymore for 1.7.

and there is no workaround? What if one REALLY needs to map function x to F10? (I bet someone has a project where they'd need all the Fx keys for mapping....)

Well, the simplest workaround is to use svn trunk or wait for 1.8. Probably can also be handled in some way with windows-api tricks, but don't really have the time to dig into this right now (it's basically solved, we can't just change old behaviour for release versions as people might depend on it and there's just a bunch of way more serious problems).

so it is solved in SVN....
that's nice. thanks for the tip
