I´m running a win7 64bit with 8gb and never had a crash only some rare disconnects (like once in an evening) and mostly the moment I klick the leave station button. I also checked the RAm useage it´s around 45% so its 3,6 GB. I conclude that if I would run on a 32bit operating system to expect crashes due to the amount of addres ram. IMHO the ram usage is not optimized and It might be worthy to investigate. but this is pure speculation. as always if you have hardware above the minimum or optimum you will/might escape such issues.
