SYMPTOMS
When the following sequence of events occurs, the QB.EXE editor causes the fourth line to be overwritten by the third line; therefore, the information on the third line is duplicated:
- Run QB.EXE and type the program example shown below.
- Type an additional word on line three following BULL.
- Try to move the cursor down one line with the DOWN ARROW key.
- Clear the error message; press ENTER.
- Use SHIFT+UP ARROW to highlight all lines.
- Press the TAB key.
This problem appears only when an error occurs prior to performing the text selection step.
STATUS
Microsoft has confirmed this to be a bug in the QB.EXE program provided in QuickBasic Versions 4.00, 4.00b, and 4.50 and to the QB.EXE program supplied with Microsoft Basic Compiler Version 6.00 and 6.00b (buglist6.00, buglist6.00b) for MS-DOS and OS/2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
