It doesn't need much memory to run, its more CPU intensive, as its taking lots of screenshots of your PC desktop and reducing them, then encoding them as JPEGs. I could put a switch in the server which will allow it to use less CPU time for those of you with older computers, either by not using as high quality resizing or by slowing the refresh rate. What CPU do you have and what speed? (Go to My Computer->Properties or System Information under accessories to find out) Ok my computer is a Dell DIMENSION DIM 2400 Intel ®. Pentium® 4 CPU 2.20 GHz 2.19 GHz, 768 MB or RAM. I hope thats the right information. BTW i am pretty sure that it isn't my firewall becasue i have turned it off and have closed other applications that i have that have shileds or firewalls.
