Hi
I have been using X3 for years, then decided to upgrade to 4 which I did, however I stopped using X4 as I could not see the Fonts display in the fly out box as they show blank so you can not see what the text would look like say in 'Bold' or 'Italic' or in a different font. I keep trying to sort it then I just go back to X3 but I really want to use X4 (I have X5 which does exactly the same thing.) I have looked at the 'Font settings' in X3 & compared to X4 checked and unchecked boxes, still no different. I did have X4 loaded on another old computer, which I uninstalled, thinking this may be the problem. Didn't change anything, so I have just uninstalled and reinstalled on the computer I am using now but still no good. Please help it's driving me crazy. 
My operating system is still windows XP not sure if this is the cause?
