Problem with some keys in VBoxSDL

[japheth]

Hello,

I use VBox 1.52 in WinXP with DOS as guest. It works ok with the VirtualBox GUI, but for a better full-screen support I'd prefer to use VBoxSDL. However, when I run VBoxSDL, I cannot enter some keys. Affected are all keys which require the right ALT key to be pressed as well (on German keyboard, the "Alt Gr" key).

I already tried to set environment variable "SDL_VIDEODRIVER" to "directx" and "windib", but this doesn't change things. Other ideas?

Edit: Using a low-level tool it seems that pressing/releasing the "Alt Gr" key produces codes 38h/B8h only, but it "should" generate E0h 38h/E0h B8h instead.

Regards

Japheth

I cannot check this currently with a DOS guest but on Linux the AlrGr key behaves correctly: AltGr emits 0x64 for KeyPress and 0xe4 for KeyRelease. Left Alt emits 0x38 for KeyPress and 0xb8 for KeyRelease. Same with the Qt GUI and the SDL GUI.
