Value Property May Change When You Click the Scroll Bar Thumb

• Microsoft Visual Basic Standard and Professional Editions for MS-DOS, version 1.0

SYMPTOMS

The Value property may change when you click the thumb of a scroll bar. This occurs after moving the thumb by clicking one of the arrows on the scroll bar or by clicking between the thumb and the arrow on the scroll bar. The increment that the Value property changes does not always reflect the value that the SmallChange or LargeChange property is set to, as it should. This problem does not occur in Visual Basic for Windows.

STATUS

Microsoft has confirmed this to be a bug in both the Standard and Professional Editions of Microsoft Visual Basic version 1.0 for MS-DOS. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
