See the problem with the toolbar. There's loads of space below.
If I start a fresh FC session, this problem doesn't exist. But I'm not sure what to change to get it fixed. None of the normal toolbar options Tools>Define action toolbar I've tried work.
I found the issue. I'm using custom scaling of 110% and as soon as it's using the standard built-in presets, it works.
It's strange how the fresh FC session doesn't have this problem with the standard toolbar. It does, however, have this issue with favourite toolbars.
Also, see this thread now that I know the problem where Marek say it only supports the defaults. https://freecommander.com/forum/viewtopic.php?t=8084
Here's the image of the toolbar.
