Centering pause commands on a particular form can be an exercise in futility because you can't know the exact height and width of the pause popup beforehand. I've gone to doing the following approximation:
1. Use the form TOP, LEFT, WIDTH and HEIGHT to calculate the center of the form. 2. Subtract a reasonable amount from that to calculate the top left of the popup. When centering on a particular control it gets lots more complicated.. Basically you have to use the properties of all the containers, starting with the form and it's client area and drill down to find the exact screen location for the control. It's lots of detail work to be avoided unless it is absolutely critical.

As far as I know, top right, top left, bottom right and bottom left work fine. What I want now is top (and bottom) central but I can't find a way to make it work. And, presumably, for left and right central I would simply reverse the co-ordinates with appropriate adjustments. Looking at what I originally set up in my variables I left out whichever one was the central parameter, eg: for vPos_Top_Left I use | TOP 10 | LEFT 10 and for vPos_Top_Centre I thought | TOP 10 | would work. I do realise that I can position the display "manually" by trial and error with the correct number of pixels from the left but is there a way to let R:Base do the central positioning automatically? Any guidance gratefully appreciated. Regards, Alastair.
