Subscribing as I hope this covers my problem as well..
I started using WampServer on both my workplaces a couple of weeks ago, and have had connectivity issues from the start... (hasn't made me go back to Xampp though
)
I too get the 'Waiting for localhost', and then nothing... .
But this does not happen each request... some go thru, and give back a response... sometimes it takes a couple of seconds (running on an Core i7-2600k with 16Gb and Wamp on a SSD, so it should fly), sometimes it doesn't give anything...
Most of the time, just refreshing helps, but it gets pretty irritating if I have to hit F5 a couple of times before I can review my changes
Hoping that there is more information!
