Hello!

I don't know how to fix the main window frames. I don't know if only the log frame is problematic or just there are multiple problems in multiple frames.

Operations frame (350) + log frame (100) = 450 - the full height of the root frame.Why the dimensions are acting different than what I expected?

Also, I don't understand the span of the labels in the search window and why I can't enter anything when the window is active (I can't type anything in them).

Thank you in advance!

I've read the documentation but I can't figure it out.I tried to modify the height mostly since in my logic that should be the issue, but with no success.
