hm, is it possible that you still have a reference to the child you are removing in the code above ? Also, the task manager is probably not an accurate tool to diagnose memory leaks, as the memory might only be released to the runtime memory allocator, but not to the system. Have you looked at the tutorial page on memory leaks (<http://opensg.vrsource.org/trac/wiki/Tutorial/OpenSG1/Memleak>)? Maybe it gives you some hints on where to look. Please note that the website might be a bit difficult to reach, as there is some maintenance going on (see the thread titled: "Server Maintenance").
