My screen size is 1024x768 and the Moho screens do not open like that, even if I click on arrange in the windows menu.The tool and style windows were not resized in that picture. However, that is a picture of a 1280x1024 screen, so it may not look exactly like yours. Here's an example of a 1024x768 screen - the tool and style windows are exactly the same size, but things are crammed in a little tighter:
This is how Moho opens.

This is how Moho looks after clicking on arrange in the windows menu.

The main design window is under all that mess somewhere. Oh yeh, the styles window is hidden by the tool pallet window and the tool pallet window is the one with all of the cool trails from all of the other pallet windows.
These are screen shots of the tool and styles pallets only.

I can't even get to all of the features in the style pallet. Did I mention that the tool pallet and the styles pallet windows size can't be adjusted?
I only have the trial version of Moho 5 and I haven't been able to work with any of the tutorials as my display screen is a mess. I'm sure that Moho could prove to be a very good program if the pallet windows could be organized better.
Thanks
