All versions before 2.00 Build 121116 have a serious performance problem when using the administration or taking surveys. This issue resulted from a routine that (unnecessarily) checked for updates on every page call.
We would like to ask everyone to upgrade to the latest version (either manually or by ComfortUpdate) because of this performance problem. We will by next week limit the calls to our update server which will in turn might even slow this down further for affected versions so please consider to update now.
