I have been refining both the doc and the functionality of ltktest-with-cells (in the Celtk module under Cells), which mirrors the LTk demo ltktest, for a few days now adding more and more connectivity between the widgets and the main display, as one would have in a more real-world application. At this point I think both doc and demo are adequate, and anyway I will not know how to improve them without feedback, whether it be suggestions or requests for clarification. btw, thx to Frank for his report that all runs well on Mac OS X. I myself saw recent versions working on Lispworks+win32, albeit with a problem in that the spinning lines spun at a glacial rate. I would be interested in hearing if Celtk runs on other platforms. Now here is a big heads up: every once in a while, except when I am trying to make it happen <g>, ACL8 on win32 hangs when I close ltktest-with-cells. Possibly something to do with my Timer class run amok? We will see. ken
