Been using the windows build for a few minutes this morning.
It won't export a file to the Desktop. The batch processor runs, but it never actually creates a file.
Also, in the Editor, when adjusting sliders, occasionally the box that contains them seems to move under the right edge of the window necessitating that the whole right side tool box have its size adjusted in order to get it back out from under the edge of the widow. This is using the TooWaBlue theme. I'll test with the default theme later today.
