AMD Radeon Software under Windows 7 64-bit freezes when lunching and will not open, but only title bar appears with normal size or resized. Ending process and re-lunching Radeon Software a few times occasionally works and it opens correctly. This happens with 21 and 20 edition drivers, while 19 edition drivers used to work fine. As advised in another thread, I reported this to AMD, but I received no reply. Does anyone else have a similar problem?
