I've been working on a form with a grid for a few days now. It was working just fine. Then all of a sudden it doesn't work anymore - I got an error message "No table is open in the current work area." (Error #52) In the Online Help it stated "A table was not in use at the time Visual FoxPro attempted to execute a table command. The current work area doesn’t have an open table. Open a table or change work areas." That's strange because I checked Data Session and all the tables are there. Even I selected the table and tried to resume yet I got another error message "Unknown member COLUMN1". I checked the Locals window and to my surprise, the grid.columncount is 0 and there are NO column properties. How can they just disappear at run-time?
