## SYMPTOMS

Running the StreBlt GDI StretchBlt Win32 application programming interface (API) sample can cause Windows NT to hang.

## STATUS

Microsoft has confirmed this to be a problem with Windows NT 3.1. This problem is illustrated by the StreBlt sample supplied with Visual C++ 32- bit Edition. The problem was fixed in Windows NT 3.5.
NOTE: This sample was not included with Visual C++, 32-bit Edition, version 4.0.

## MORE INFORMATION

To reproduce the problem, follow these steps:

1. Build the StreBlt sample using the supplied makefile.
2. The sample displays a dialog box for the main window. There are three drop-down list controls titled StretchBltMode, Pattern, and Standard ROPs. Select the following in these drop-down lists:

             StretchBltMode    BLACKONWHITE
             Pattern           NULL_BRUSH
             Standard ROPs     PATPAINT

At this point Windows NT will hang.
