> Any ideas anyone?

This has been reported. It seems to be related to the change in VFP7 to have the _screen top, left, height, and width properties relate to the VFP desktop client area, and the _VFP top, left, height, and width properties relate to the entire desktop, including the titlebar, menu, toolbars, and status bar.

In some instances this can cause _screen.autocenter to make the top of the _VFP window to appear off the top of the monitor screen.

This should help, if you add it after your autocenter=.T. line

* Set VFP desktop top to half the difference between 
* monitor resolution height and _vfp.height
_vfp.Top = (SYSMETRIC(2) - _vfp.Height)/2
