Now this issue is a bit different. One of my moderators cannot reply to a conversation but he can if he starts his own and invites others. That is weird. I checked the account permissions and they were normal (just like the other moderators). He has a very powerful computer/ latest os (Win 7 pro, AMD Phenom II 964 Black quad core. 4 gigs ddr3. Gigabyte ultra durable 3 mobo. It's a high power gaming computer. 600watt supply. GTX260 vid card.) and latest browsers (ie 8 and firefox) and he's also tried dumping browser cache but none of that worked. He also allowed me into his account and I could reply to pcs like normal so I can confirm its a problem at the userend. Now does any have any idea what could this be. Thanks.
