SYMPTOMS

When you use the DBGrid control on a Microsoft Windows 95 or Microsoft Windows 98 Japanese edition, the ARROW key is not recognized in certain instances. If the cell contains double-byte characters, the ARROW key is not recognized. If the cell contains single-byte characters, the ARROW key is recognized and your application responds to this event.

Steps to Reproduce Behavior

Start Visual Basic 6.0 and create a Standard EXE project. Form1 is created by default.
Place a DataGrid control on the form, such as DataGrid1.
Place an ADO Data control on the form (Adodc1).
Set Adodc1.CommandType to 2 (adCmdTable).
Set Adodc1.ConnectionString to Provider=Microsoft.JET.OLEDB.4.0;Data Source=C:\Program Files\Microsoft Visual Studio\VB98\Biblio.mdb.
Set Adodc1.RecordSource to Authors.
Set DataGrid1.DataSource to Adodc1.
Run the program and click to select any cell, and put a double-byte string in that cell.
Move the cells around by using the ARROW key.
Note that the ARROW key (CURSOR key) works fine on cells that contain only single-byte characters, but does not work on cells that contain any double-byte characters.
