First of all. I've spent hours selecting the patterns and colors that I like and saved them to a theme. All themes were LOST in the latest upgrade! The upgrade wizard asked me if I wanted to OVERWRITE the existing files. I never thought that would also mean that it would delete all my themes, especially since the package does not come with a theme named the same as my last theme. Now I have to do it all over again.
Second, every time I start MCE 2005 I have to manually start the toolbar and select my theme from the theme combo box. My last selected theme is visible at start-up, but the settings are not loaded. I have to do this manually and it is very annoying.
Third, the same goes for the screen saver; it will not load my selected theme when it kicks in. I don't use the screen saver because of this.
Fourth, every time I make changes to my theme I have to save it under a new name. Come on, this is 2006, please provide a Save button. I think my last theme was named "Party 84" or something...

And last; even though I have disabled all images, videos and particles I still get the G-Force logo from time to time. I would like to have the product "commercial" free since I have already paid for it...

One final suggestion: please add a slider that will allow the users to set the intensity of the colormaps. I would be nice to be able to dim down the colors if you want to without having to create a whole new set of colormaps.
Just my 5 cents... Otherwise it's a great product
