I’m never clicking post twice. It only happens from my new cell phone not from my laptop. And every single time it happens, the progress bar (on my phone’s browser) pauses for a few seconds then completes quickly. Then, wham, double post. It appears to be a defect with the Android itself. It’s also sending two requests for some page views. I just can’t figure out why.
I don’t think it’s Android, as I pretty much post here solely from an HTC EVO. I do, however, use Dolphin HD for a browser, as it’s much more complete than the stock one.
Perhaps you can try a new browser?
