BUG: Cannot Navigate Columns If a Row in a Grid is Disabled

MORE INFORMATION

Steps to Reproduce Behavior

1. Create and populate a table as follows:

         CREATE TABLE test (fld1 N(5), fld2 c(5))
         INSERT INTO test VALUES (85000,"aaaaa")
         INSERT INTO test VALUES (90000,"bbbbb")
         INSERT INTO test VALUES (75000,"ccccc")
         INSERT INTO test VALUES (60000,"ddddd")

2. Create a form and add the table to its data environment.
3. Drag and drop the table from the data environment onto the form to create a grid.
4. Place the following code in the grid's AfterRowColChange event:

         IF test.fld1>80000
            This.Columns(ncolindex).Enabled=.t.
         ELSE
            This.Columns(ncolindex).Enabled=.f.
         ENDIF

5. Run the form and use the Down Arrow key to move to the record that has 75000 in the first column.
6. When the cell containing 75000 gets the focus, it is disabled.
7. Use the RIGHT ARROW, LEFT ARROW, or TAB key to move to the leftmost or the rightmost column in the row.
8. Once the focus is in the leftmost or rightmost column, using the LEFT ARROW, RIGHT ARROW, or TAB keys, try to move to some other column. Note that you will not be able to move to another column.
