Are you aware of issues with Lightstreamer leaking memory in Firefox and IE? There has been alot of publicity lately with the advent of JavaScript heavy sites causing IE to leak, especially if event handlers are not garbage collected properly when no longer required. We have found that Lightstreamer leaks in Firefox. Are you investigating this issue for the next web client release? Is there anything we can do when initialising and integrating Lighstreamer to reduce the leak effects?
