Hi Benjamin, Could you set the default left pane width to the possition of the splitter? If I set, for example: SplitterPos = 40 then the splitter is right where I wanted it to be, but the left pane is not fully used. I know it's hard to understand what I mean, so here's a picture: I wish the width marked with the red arrow would be as set by SplitterPos. Hope you agree with me. Thanks.
