I am not sure if WGT knows this is still a problem since they haven't responded lately. But it is. It's not the browser or the cache or anything on our pc's. As I stated in my previous post, I play with a group of guys on Ventrilo. We get a group of 4 guys together to play Alt Shot. One guy sends out the invites. We all know the invite is coming and are waiting for it. We are all green and available. Sometimes out of the 3 invites that are sent out only 1 will get the invite. So then we change the person to send out the invites. There are times we have to go through all four of us before the last person can get the invites sent out to all the players. Just last night I sent out the invites and all of the other 3 could not get the invite. We have tried restarting our browser, changing browsers and rebooting our pc's. But this has no effect. The one thing we have found is that this problem happens when the player that is sending the invites, it is his first game of the day. Maybe that bit of information will help you WGT.
It would be nice WGT Icon if you would acknowledge that this is still a problem that you know about and are still working on. I understand it may be a complex problem and WGT is having a hard time figuring it out. But at least let us know.
The next time I have the problem of my invites not being seen, I will go and play a quick blitz and come back and send invites out again and see if that solves the problem and let you know.
