- The solution to your problem is built into SC 1.6. Just use the script
- on mouseup
- global vol --volume path contains: Hard_Disk:Roger:
- set the picturedata of cd grc 1 to vol & "butterfly" -- this assumes
- you have a draw rectangle as cd grc 1
- set the topleft of cd grc 1 to 10,10
- end mouseup

- The error in QTPict seem to be the same as was in an early version of
- QTMovie, which they fixed.
- The programmer had left some HC 2.x specific code or callbacks in. They
- fixed this in the 1.0 version.
- The real trick with SC is to bring up a single frame of a movie as an
- object. I had to write my own
- XCMD to bring in the poster frame as a bitmap so I could put overlays on
- top of it. The QTMovie
- XCMD (version 3/19/92) seems to still have a bug in putting a poster frame
- which is not the
- first frame into the clipboard.
