This was most useful, and educated me, and I wrote several progs using multiple images.
I then wrote a program with a single well sized and placed image (150kB) and used a mouse to overlay single characters at different print positions.
I was ecstatic. A dream come true. Then I hit the wall.
4 clicks and a freeze, and my cpu fan went crazy.
The ground started shaking. Was it an earthquake?
No, it was the QB64 reality helicopter landing on my dream.
I had to use task manager to escape.

You have solved my problem, but introduced me to a beast, now I will have to open another thread about freezing to avoid going off topic.

[fortunately there are no bugs in QB64, only 'undocumented features', or 'glitches'  :) ]

Thanks for your reply.
Where can I find your chess program?
