Hi
It looks ok to me, by which I mean all the letters with purple background are in the words you specified. It took me a while to find them all but if you look at the attached file you can see that all the words are there. Note that words can read from right to left and bottom to top.
The only glitch I could see is that the bottom two rows of letters are separated from the ones above by a white gap, which admittedly makes it more of a challenge. Maybe one of the Xerte developers can shed some light on that aspect?
I believe you may be a member of staff at UWE. If so, please feel free to contact me on Dit e-mailadres wordt beveiligd tegen spambots. JavaScript dient ingeschakeld te zijn om het te bekijken. if you need any further help on this.
