buglist3.00 fixlist3.10

Summary:

PROBLEM ID: WIN9012005

SYMPTOMS

Under enhanced mode Windows version 3.0, when a multiple document

interface (MDI) application creates a maximized MDI child window

with at least one visible scroll bar, the application terminates

with an unrecoverable application error (UAE). When Windows is

running in standard or real mode, Windows reports a fatal exit

0x00FF.

RESOLUTION

Microsoft has confirmed this to be a problem in Windows version

3.0. To avoid this problem, specify the desired scroll bar style(s)

when the MDI child window is created. Then set the scroll range for

the scroll bar(s) AFTER processing of the WM_MDICREATE message has

completed.

This problem was corrected in Windows version 3.1.
