NUM LOCK On; ALT+BACKSPACE Fails on IBM PS/2 Model 50 and 60 (40369)






This article was previously published under Q40369

SYMPTOMS

When Microsoft QuickBasic Version 4.50 is running on an IBM PS/2 Model 50 or 60, the following key sequences fail if the NUM LOCK key is on:

  1. ALT+BACKSPACE fails to UNDO editing (i.e., pressing the BACKSPACE key while holding down the ALT key).
  2. ALT+[-] or ALT+[+] fails to size the window (i.e., pressing "+" or "-" while holding down the ALT key).
If the NUM LOCK key is off, the above key strokes perform as documented.

STATUS

Microsoft has confirmed this to be a bug in Version 4.50. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
