Hi. I am a total newcomer to Pixelinsight. I tried out the trial version (can't remember which version put probably the one prior to 1.8.8). In that I could move and resize previews with the mouse cursor. I then bought and downloaded the 1.8.8 version. It now seems I cannot graphically edit the preview size/position, but only specify Left, Top, Width, Height numerically. Am I missing something obvious?
