Some applications don't interpret taps on touchscreen correctly


Hi!
I just installed Chrome, and so far I only have one complaint. My laptop has a touchscreen, and when I tap on a link, it acts like I only moved the mouse, but didn't click on it. I've noticed similar behavior in other applications, and even in my window manager (awesome). Is there a global setting for how the touchscreen should be interpreted, or something similar?

Thanks!

I thought with touch-screen on a desktop OS the first tap moves the mouse pointer and the next "clicks". I know that's how VLC clients for iOS tend to work and I can't think of any other way of doing it with a mouse and touch screen present?
Edi: iOS does something similarly natively in that a tap isn't always designated as a click especuially if it's not done precisely on the link. Blackberry OS (the old one) mixes pointer and touch so does similar. Can't recall how Android does it.

A touch screen is a mouse for most things.

I'd assume that the computer is under load and your tap may need to be more of a hold to get it to read the request correctly.

So how does one usually move the pointer?
I'm tryig to imagine XFCE4 with a touch screen and wondering what it does about things like text selection and missing the URL deliberately.
I know this old Blackberry has some odd conventions and Windows Phone Edition was even stranger but, to me, more straight forward than iOS.

Thanks for the replies!

I've usually seen what 273 described: the mouse moves, then clicks on wherever I tapped.

I highly doubt that it's a load issue. I have htop open, and all 4 cores are staying below 5%, I'm using roughly 1/16th of my RAM, no swap usage, and I'm not seeing any change in behavior. So if it's load-related, that's one very picky touchscreen.

I should probably mention that it's a Dell Inspiron 15R laptop that came preloaded with Win8.

Thanks!

EDIT: Also, it's the entire browser (scroll, tabs, settings menu, etc.) that fails to react to taps, not just the webpage.
