SourceTree v3.4.23 interactive rebase dialog opens with very large size.

[postonly]

I just updated from v3.4.21 where the interactive dialog window opens with a normal size compared to the parent window. With v3.4.23 the dialog opens and extends out of the parent view panel with no scroll bars. The only way to get to the buttons at the bottom is to expand the size of the SourceTree parent window until I can see the entire dialog window. Now .23 takes up most of my monitor space if I want to do an interactive rebase.

Is there a setting or some way to go back to how .21 handles the dialog??

Thanks in advance for any advice.
