Re: [h-e-w] Is anyone using both meta and alt on w32 or linux builds?

[Lennart Borgman]

We have been through this various times on Emacs lists. As I
understand the docs at MS this should not work. In some cases it
might, but you cannot expect it to work reliably. You need the patches
in EmacsW32 for that (and even then there are some troubles on Windows
7 - some meta key combinations can't work because the OS takes them
before even you can grab them at low level).
