According to MS KB Q95232 at http://support.microsoft.com/support/kb/articles/Q95/2/32.ASP?LN=EN-US&SD=gn&FR=0&qry=Q95232&rnk=1&src=DHCS_MSPSS_gn_SRCH&SPR=CHSPRB: Video Card Causes GP Faults or Display Problems "A number of video cards do not work properly with FoxPro for Windows. They may cause general protection (GP) faults or display problems."

>I am having trouble with objects(ie, grids, text boxes) on forms that on load they are read only or not visible until I allow the user to edit them. My problem is that if a object is read only or not visible on load then it will be grayed out even if I make it editable. I have sort of narrowed it down to machines using ATI's Rage Video cards. When the client updated the drivers it corrects some of it but most areas stay grayed out. You can not see what is there or what you enter there, BUT what every you enter there will be stored correctly. Any help would be appreciated.
