@m5dude Thanks!
Sorry about comments absence in code - they was on local language, and dropped automatically when downloading. Code optimisations was only on chess engine, other parts made more rudely.
@world101 Really glad you raised this question and found a solution... I have wanted to use it for quite a while but hadn't chased it.... thanks. Will test it out.
Glad to hear our issue is cleared.... its understandable for anyone if one has had issues with something in the past to be sensitive - even more so when digital rights are involved as this can quickly become a serious matter.
I think I have some similar views to yours in that area.
OK well all the best with your work..... I stay tuned ! Jimi
