the bottom bar should be at the bottom. But to easy troubleshooting in these cases the ProfitUI Control Center now has a new function. Open it up and copy'n'paste the following into the textbox:
parent.parent.ProfitUI_BottomBar.Location=0,200
and hit "Execute Script". Your bottom bar will be placed in the upper part of the screen. Move it from there. If it is hidden hit F10.
For the XP window just play with the window settings, nothing was changed.
