>The only problem I have encountered with the TechPreview (I have not yet istalled the beta1) is the when going back to VFP6 all fonts are about 1 point size. A whole page of code fits into the top 1/" of the screen. When I go to change the font it is set to somthing like -65000

Actually, if memory servers, that problem is unrelated to installing 7.0 in conjunction with 6.0. I had it happen on one or two of my boxes, but it went away by itself, so I never pursued the issue. I do remember that it happened on a box that hadn't yet had 7.0 installed, so I assume the two are unrelated.
