I'm using DisplayFusion now for about two weeks and I'm very happy with it. I used UltraMon before, but wasn't happy with the look of it under Vista. Now I use Windows 7 (64 Bit) and UM failed even to install. DisplayFusion works fine normally, but today I encountered an error after I had my computer running for about two days. DisplayFusion used about 800MB of my RAM (there are 8GB so this is no big thing at all) and my computer was nearly unusable freezing for about 30 seconds before I was able to do something else (still I was able to move the mouse). After I clicked the DisplayFusion taskbar on my second monitor Windows asked me to stop the process which I did. After that everything worked fine again even after I restarted DisplayFusion (now only using 18MB of RAM). Any ideas?
If you are a Pro user, I would like to invite you to join the beta testing team. The new version (3.1) has some significant improvement in resource usage. I would be interested to see if it corrects this problem. I'm going to mark this topic as "Complete" for now, but I will continue investigating with the beta program. Thanks!
