do you mean PSP 7 or PSP X7 ...

PSP 7 is like before the ark I go back a bit and I only remember ver 9 [before corel took it over from jasc]

in any event you probably can't get the program to add the pattern fill style the way you want it as you type - Im guessing here, but I think you will need to type your letters first and the select all [maybe group] and then apply style

you might be better off asking in a corel forum.... if you can't get this to work...
