With some programs, though not all, I have to actually click and drag the window to get the graphics to display. Here is one where I had to move the window. Any thoughts? Thanks!

sync on
hide mouse
sky=1000
make object sphere sky,300
scale object sky,-100,-100,-100
fog on
fog distance 100
fog color RGB(0,0,128)
maxBox=100
for boxVal=1 to maxBox
make object cube boxVal,5
position object boxVal, rnd(100), rnd(100), rnd(100)
next boxVal
position camera 50,50,0
sync
wait key
end

You need one extra SYNC in there - the first SYNC doesn't display anything (due to double-buffering I believe).

Moving the window forces a redraw, in effect carrying out a partial SYNC.

Thanks, it works! Anything you can tell me on how I can know when I need to sync multiple times?

There's no obscure rule for this - all syncs from the second one onwards will update the display.

TBH though, in the code you posted, I could have easily suggested remmoving the SYNC ON command.
