Sorry to bump such an old thread but I just wanted to point out that I am also getting the same odd collapsing behaviour on the log output text at the bottom. Trying to resize it at all results in it being forced collapsed with no way to reopen it other than a kstars restart.
The main reason I am posting though is regarding the 'Independant window' option for ekos. I have enabled this checkbox for both the indi window and ekos. It works as expected for indi, but the ekos window remains as it was before -- bound to kstars and without the minimize or maximize buttons in the top bar.
