not working - perhaps ahk version issue?

[alanbork]

I can install and run, but mouse clicks don't seem to be sent reliably. for instance if I open up MS paint and try sending a RMB I don't get a context menu. Fails in games too, but I figure we all have MS paint so that's a better test case. I do get the set of icons around the edge of the screen, but I assume that's part of the C# code and not from AHK?

I'm hoping it's something simple, like which version of AHK (1, vs 2, and which release) is required? The fact that it partially works suggests some deeper problem, though.
