So it looks like ZBrush is covering up the Windows taskbar for whatever reason. Is there a way to get it to not do this? I would like to be able to see the time and switch applications easily.
Even though the task bar is covered you can easily view it at any time by pressing the Windows key on your keyboard. This has the advantage of maximizing your screen real estate while still allowing you to get to the task bar any time you wish.
If you do want to have it always visible the way to do this is to resize the window to how you wish. Click the Restore button at the upper right corner of the window, just to the left of the Close (X) icon. Now use the title bar to drag ZBrush to the upper left corner of your display, then use the lower right corner of ZBrush and/or the window edges to drag the window out to the size and position you want. You’ll want to finish with it taking up the full width of the screen and everything vertically except the task bar. Now press Ctrl+Shift+I to save your preferences. Since ZBrush is not maximized, the preferences will store the window size and position for all future launches.
