I made two similar apps, each with a data display form created with the one-table wizard. I then replaced the buttonbar with my own modified version. As far as I know, I didn't change any code related to table buffering. Each buttonbar has a Save and Revert button using TableUpdate and TableRevert. In app#1 they both work. In app#2 the Save works but Revert gives a "table buffering must be enabled" error. I discovered that the wizard never put a CURSORSETPROP command in, so I thought, fine, I'll put one in. But I wonder: Why do both Save and Revert work in App#1, and why does Save work in App#2?
