I'm on Windows 7, 64 bit. I've been using previous versions of x-lite for years and never noticed this problem. The initial footprint for 5.0 when I load it is around 120,000 (seems much larger than before although I don't have a record) and then grows over time so that within a day its over 300,000. Anyone else see this problem. If anyone from Counterpath is reading this, can you tell me it this is a replicable problem and if you plan to address it?
