I'm using XP SP2 Discovered the text scrolling issue on the second day after purchasing the logomaker. I'm running Norton (Symantec) AV and Firewall 2005 I don't recommend that anyone go without some kind of protection while online. My logo maker prog works just fine while Norton AV and Firewall are running. I discovered that in my case it was the enhanced security features that have been written into SP2 (windows) I turned Windows Security Centre off in order to get the logo maker to work with regard to scrolling fonts. Here's what I did: Click "start" scroll to "run" Typed "msconfig" into the box and clicked "enter" Once the msconfig box came up I went to the "services" tab, clicked on it and scrolled down to where it says "security centre" and unchecked the box. Next I clicked on the "startup" tab and scrolled down and unchecked the boxes for - "ltmsg.exe", "mmtask.exe" and KBD.exe and then clicked apply. Then I clicked O.K. and rebooted my machine. I can now scroll all 2500 of my fonts whether they be system or embedded. I am really not going to miss Windows security at all really as I feel that after using Norton for years, it is a much better prog anyhow.
