The first problem I had was I could not create new folders when saving. I kept getting, "path cannot be found". So I go in the Windows directory to the "Chases" folder in Freestyler and create the folder myself. Go back in Freestyler and try to save again. It takes it this time. This of coarse was annoying for each folder I had to recreate.
The second problem was I had to click new sequence, click save and name it before I even clicked on the first light. I would get "path not found" if I didn't do it that way. Weird. So now the new sequence has a name, but I had to literally click "Save" and overrite the file name for each change I made on each light in the sequence. The quick save wasn't working either. After creating a seven step sequence and all was the way I wanted things, I click save again and save to cue.
The third problem - when running the sequences from the Cue window, the dimmer channels for the moving heads would go to zero. The heads would move the way I programmed, but no light output. Close the Cue, open the sequence from the sequence builder and the dimmer channels are back to 255 just like I programmed it. Close the sequence builder, open Cue, dimmer channels back to zero in my sequence. I tried clearing the Cue list and add everything back to the Cue again, but dimmer channels still zero when running from the Cue window. WTF !

I added the saved Cues to the Submaster anyway and the dimmer channels would open sometimes, but mostly not. I go back to the sequence builder and all works fine, just like I programmed it.
After trying 3.0 on two seperate computers (laptop and desktop) and 4 solid days of fighting with it, I uninstalled 3.0 and reloaded 2.96j.
