Hi, Could someone kindly help me on the following question? Thanks a lot in advance! I used redhat 8.0 and the QT 3.0.5 was automatically installed when I installed the redhat. Now I want to upgrade QT to 3.3.4. My questions: 1. Is there a QT 3.3.4 RPM file? 2. Because I use QT in other softwares and applications. If I upgrade QT but it does NOT work with other software, CAN I go back to my old QT version? Thanks very much. Yours, Beifang __________________________________ Discover Yahoo!
