Known Issues in 4.5.3

Windows Software Issues

• When building Qt 4.5.0 with Windows 7, the build fails with an error message regarding failing to embed manifest. This a known issue with Windows 7, explained in the Windows 7 SDK Beta release notes. A workaround for this issue is to patch the embed_manifest_exe.prf file with the following:

   diff --git a/mkspecs/features/win32/embed_manifest_exe.prf b/mkspecs/features/win32/embed_manifest_exe.prf

• Under certain circumstances Visual Studio Integration v1.4.0 will not be able to install the integration for Visual Studio 2005 on Windows Vista. An error message states that .NET Framework v2.0 Service Pack 1 is not installed. This is due to a problem with the built-in installation of this on Windows Vista. This issue can be fixed by installing .NET Framework version 3.5.
• With NVIDIA GeForce 7950 GT (driver version 6.14.11.7824), a fullscreen QGLWidget flickers when child widgets are shown/hidden. The workaround for this is to use setGeometry() with a width/height 1 pixel bigger than your geometry and call show().
• A bug in the Firebird database can cause an application to crash when fbembed.dll is unloaded. The bug is fixed in version 2.5.
