This topic has been discussed in other threads, maybe you could do a search. In fact, Vue 7 has a higher memory overhead than Vue6. That's only natural, each new software version of almost everything demands more from the hardware. So, unless you upgrade your hardware (or change it...) you'll have problems. Your system is a bit outdated. A 32 bit system and 3GB is something of the past... :-) If you upgrade to 64 bit system and 8 GB RAM (like I and many others in this forum have done) you'll see a ton of difference. In this case, you won't see any deterioration of performance, quite the contrary, Vue 7 is much faster.
