3-D feature space plot missing or not updating correctly

Tech Note: TN0876
Product: OpenController, OpenSorter
Version: All
Date Added: 2010-10-04

Issue

When using Windows Vista or Windows 7 machines, the 3-D feature plot in OpenSorter or in OpenController's PCSort window may be missing or may be erroneously highlighting waveforms.

Workaround

If the feature space plot is missing, turn off "Threaded Optimization" for the affected application(s). This setting can be found in the NVIDIA Control Panel and is set on a per-application basis.

  1. Right-click the desktop and select NVIDIA Control Panel on the shortcut menu.

  2. Within the NVIDIA Control Panel, select Manage 3D settings.

  3. Select the Program Settings tab and find the affected application(s).

    For OpenSorter, add C:\TDT\OpenEx\OpenSorter\OpenSorter.exe.

    For OpenController, add C:\TDT\OpenEx\Controller\OpenController.exe.

  4. Turn the Threaded Optimization setting to Off for the affected applications(s).

  5. Click Apply and close the NVIDIA Control Panel.

  6. Restart the affected application.

In OpenSorter, if previously selected waveforms remain highlighted in the feature space plot even though they are no longer selected, turn off the advanced visual settings for that application.

  1. Navigate to **C:\TDT\OpenEx\OpenSorter**

  2. Right-click OpenSorter.exe and select Properties on the shortcut menu.

  3. Select the Compatibility tab.

  4. Select the checkbox Disable desktop composition.

  5. Restart OpenSorter.

Solution

Upgrade to v2.18 or later.
