I have just updated my Mac laptop install with v6.0.1. The upgrade went through quite happily.
Unfortunately there is a new bug that did not occur in v6.0.
I have my focus window set at about 2/3 width and my property window fixed at the remaining 1/3rd on the right. If I select the map window the window opens up as usual with the existing problem unfixed of no properties available on the left side of the map. If the map window is then closed with the X top right it disappears and the focus window is again shown, however the focus window is now maximised and the properties panel is turned off. If you then minimise the focus window the map window is also visible at about 1/4 screen size below the focus window and it can then be closed for a second time. The properties box has to be opened and the focus window resized.
On v6.0 this did not happen.
For information. I am not sure that it is worth reporting as Crossover and Mac are not officially supported. It looks to me that v6.0.1 is a retrograde step for those on Crossover and Mac so I suggest holding off on the update.
