Version: (using Devel) Compiler: g++ 4.3.2 OS: Linux Installed from: Compiled sources When a user logs in etc. often my machine hangs and then the task bar vanishes and re-appears a few seconds later. This almost always happens when someone messages me and I click chat/ignore, but also happens when people go online/offline.
