column window not visible

Hi,
on my win7 laptop (1366 x 768) with the latest HeidiSQL Version
i don't see the column window for a table.
I do see GENERAL and COMMENTS, but not the individual columns which is usually below.
Also dragging borders etc does not help ..
Any idea?
Thx
Stephan

That sounds like the columns are hidden because the history log is too wide opened - make it less high so you see the columns again like here:
