That is really weird. We don't really have control over that, per se, as it seems to be your desktops' problem. You can try [Alt + Space] then like maximize or size to alter.
Or try other Windows resize options, including forcing an argument in the file.
Sorry if we have to force that on you, but this really outside our development. Maybe down the road this get fixed for the full version, but we are unsure why this happened to you.
