BUG: Pressing INS, DEL, HOME, or END Key Causes Cursor to Jump

ID: Q110119

The information in this article applies to:

• Microsoft FoxPro for MS-DOS, versions 2.5a, 2.5b, 2.60a

SYMPTOMS

Pressing the INS, DEL, HOME, or END key when the currently selected object is a popup (selected but not activated) will cause the cursor to jump to the first check box object in the active window.

Pressing the INS, DEL, HOME, or END key from a radio button or other push button set will cause the cursor to jump to the first push button set defined on the screen and execute the push button's VALID clause.

This behavior does not occur in FoxPro 2.0 or 2.5 for MS-DOS.

RESOLUTION

Popups

See "Example 1 - (Popup)" below.

To resolve the problem demonstrated in Example 1, you must redefine or disable these keys through the ON KEY LABEL command.

Push Buttons

See "Example 2 - (Push Button)" below.

To resolve the problem demonstrated in Example 2, either make the same changes as for Example 1 or define a hot key ("\<") for each push button prompt.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Problem

Example 1 - (Popup):

Run the following program, and from the selected popup object press the DEL, INS, HOME, or END key. The cursor will jump to the "Check Box 1" object. Please note that the keys behave as expected if the popup is activated.)
