Performing a global reset can solve many small issues that happen with lighting fixtures. When something is acting odd with the lighting fixture, the first line of defense is always a global reset.
Right click on the desired fixture
Click OK in the pop up menu and verify that the fixture is resetting
Verify that the fixture is resetting by watching for it to blackout, and start to spin around slowly.
If the fixture did not blackout and start to spin slowly, there is still hope! Please follow the steps below to correct this and reset the fixture.
Verify that the offending fixture is selected. If it is outlined in yellow, it is selected!
If the fixture is not already selected, just click on it once and it will highlight yellow, indicating that it is now selected.
Navigate to the Patch View.
Take a look at the top left of the Vista window. The patch view is opened by clicking the square that looks almost like "connect the dots".
With the patch window open, change the macro timing.
Click the right arrow that is highlighted below to scroll through the tabs until you see "Macros".
Once the "Macros" tab is viewable, select it. Change the last number in the RESET area from 2000 to 10000.
The Reset timing should now show "17@205#10000".
Try to reset the fixture once more after this setting has changed. The fixture should blackout, and start to spin slowly.
