As luck would have it, a customer sent in a Space to us where H9 Control would crash when he tried to save its preset list. I looked at his Space and was able to reproduce the problem on a Windows 7 machine. The cause of his problem is he had a preset saved on his Space which had a character in its name which was illegal to use in a Windows file name. More specifically, he had a preset named 'Size*Matters', and the '*' is illegal in Windows file names. This might explain the crashes some of you have described when saving preset lists on Windows as well. In any case we'll put out a new build of H9 Control tomorrow that fixes this problem and also has the crash reporting feature.
