Win7 64 with cubase 5.5.1 ....
1 Knobs couldn't be turned in the Matrix section. (Previous beta version worked fine)
2 Pressed the x / + only shown the English not the symbol.
3 Matrix 1-8, when you change the "T" by using mouse click and then played some notes. Note sustains forever.
e.g suppose "T" is set to "Layer 1 Voice Volume" where "S" = ADSR env. If you click on them and change the setting and then played a note. Note sustains forever.
4 save patch without extension
e.g New -> default sound -> edit the patches -> save as "filename = haha". Browser couldn't see this new patch. It turned out I need to add the extension to it (haha.smpr). Reload the SM and then it appears...
Edited : fyi, I am using Orange skin
