I have recently been experiencing strange symptoms while using viewer 2. I find it difficult to move around and and stepping off the slightest edge, such as going down stairs, cause the falling animation to play. Also, clicking on folders in my inventory cause a one second delay before their content is displayed. After noticing these , I progressed through a number of attempts to solve this. I have cleared my cache. I have uninstalled all LL viewers, and tried new, clean installs on both a PC and an iMac. The symptoms persist when using either machine. My inventory has exceeded 18,000 items in size. Can a large inventory count adversely affect viewer 2 performance?
