I hope so. But why are you using Qt 4.2? I mean hundreds of bugs have been fixed the last 3 years in Qt and many new features were added. I provide a Windows build and therefore use the most stable version of Qt and a full featured LyX.
(I use Qt 4.5.2 and Qt 4.4.3. Having installed also Qt 4.3 ans 4.2 would be a pain.) I propose to require Qt 4.4.x or at least Qt 4.3.x when compiling LyX. Would that be OK? regards Uwe
