When just sitting on a poseball, chatting, the whole system freezes, and I cannot type, click, see the cursor, move or change window or anything. The avatars also stops moving, if the poseballs uses an animation, the sound even "hangs". Then after about 5 seconds the system works smoothly again for another 10 to 15 seconds. This is only happening to me with the latest RC viewer (1.20.2) so now I use the old regular client. On this version the CPU usage is double the amount of what I get from the regular client. http://blog.secondlife.com/2008/04/18/new-release-candidate-viewer-120-rc2-available/#more-1924 Read the posts # 25, 26, 57, 121, 126, 131 and 132 on the blog. I am not the only one having this trouble.
