The Qt version from lyx-windows-deps-msvc2008 (4.3.0) doesn't match the AltInstaller (4.5.3). Having a precompiled Qt is such a wonderful luxury. Is anyone so generous as to share their updated library files?
Qt versions from ftp://ftp.lyx.org/pub/lyx/contrib/ : 4.5.3: AltInstaller 1.6.5 4.4.2: lyx-windows-deps-msvc-qt4 4.3.0: lyx-windows-deps-msvc2008: -Ben
