I had tried that as my first attempt. But when I typed a space, no output would be sent to the display value. I could tell that the space was being trapped and the dodefault was being called, but no output would occur. I guess for the dropdown combobox that there is a bug in the dodefault call.

I had tried 255, but for the Arial font, it is a y with two dots above it, so that character didn't work. I tried the FoxFont but the point size did not work well with the display. I have not experimented with other fonts as the normal font that I use in the forms is Arial. I have thought about creating a custom Arial font (I have a font editor) and modify the 168 char to look more like a space (probably have to have something in it to keep the control from trimming it).
