That more or less solves the main problem, thanks, I just have a couple of details to clean up, here is some example code; REBOL [] inform-and-process: func [ dlg [object!] fun [function!] "Function to be run, passed the progress dialog wrapper" /offset where [pair!] "Offset of panel" /title ttl [string!] "Dialog window title" ][ dlg/lay/text: copy any [ttl "Dialog"] dlg/lay/offset: either offset [where] [system/view/screen-face/size - dlg/lay/size / 2] dlg/lay/feel: system/view/window-feel dlg/show fun dlg dlg/hide ] my-progress-dialog: make object! [ progress-bar: none lay: layout [ txt "Process in process, please wait" progress-bar: progress 200 black red] set-progress: func ["This doesn't appear to work" val][ progress-bar/data: val show progress-bar] show: does [show-popup lay] hide: does [hide-popup] ] my-func: func [dlg][ wait 1 for x 1 100 1 [ dlg/progress-bar/data: (x / 100) show dlg/progress-bar ;dlg/set-progress (x / 100) wait 0.05 ] ] inform-and-process my-progress-dialog :my-func You'll see that I prefer to wrap the layout in an object to keep everything nicely wrapped. It does require that I agree a protocol with myself but I'll manage. What I do wonder though is why the commented out line in my-func does not update the progress bar in the way that the two preceding lines do? Secondly, how would I set up an event handler to make the dialog un-closeable? cheers Andrew
