Tap on Windows 8 touchscreens doesn't work

Has anyone run into this using GLFW apps on Windows 8 with touchscreens? I have to double-tap things that are a single tap on any other platform. It works correctly on Win7, and it works correctly in a Win8 Metro app.

Maybe it's something related to DPI settings? I remember hearing something like 'wrong tap detection' (as in wrong position) on win8/touch in Blitzmax.

Positioning is correct. It's that what is a single tap or click on other platforms is not registering unless I double-tap.

I went looking in the touch settings and didn't see anything that seemed like it would relate.

On Windows 7 or 8 in GLFW, TouchDown() does not fire unless your finger moves a bit. But the OS sees the tap -- the little "feedback circle" shows up.

I'm going to post a bug report.

I'll look into this, but it's worth noting a 'tap' may not register as a touchdown if it's fast enough (or the OS is slow enough).

Mark, I posted repro steps and sample code in the bug report forum. Touch duration didn't seem to matter.
