Digital Light & Color

I do not know if it is not just a quirk of my PC.

1. Open an image
2. Run Test Patterns -> Checkerboard and click Cancel or "x" button.
3. Run Test Patterns -> Checkerboard again and click OK
4. Close the checkerboard thumbnail ->
The remaining input image thumbnail does not regain focus and canot be displayed in the image area.
Since that moment whatever second image is added and removed, the input image, if alone in the Browser, does not regain the focus.

5. Close the PWP8
6. The PWP8 will not start unless you restart the PC first.

Additional observations:
The same happens with Step Wedge and Texture - transformations independent of the input image.
But if any of the other transformations is run at step 3 there is no such problem.

It seems as if the order of the thumbails in the Browser also plays some role. The thumbnail images of the three mentioned transformations go before the input image while the others go after.

The input image focus can be regained by dblclick and Cancel button of the Replace Existing File box, or the mouse right click, still it does not help if the image is the only one in the Browser.

The PWP8 will not start even when you close the "culprit" image first.

One more remark:
I just tried to overwrite the PWP 8.0.exe file with the new but the access to the previous one was denied. It seems to confirm the fact that some processes go on the backgroud when PWP8 is closed in the situation described above. Restarting the PC solved the problem as expected.

It looks like it is going into an infinite loop when trying to shut down. Instead of restarting your computer, you can go to Task Manager and end the rogue copy of PWP manually.

Jonathan, you mean to go to Task Manager before closing PWP or after? Because I had the same idea but could not see anything reminding pwp to end either in Aplication or Processes. The only way was restarting PC.

After closing PWP down, if you go to Task Manager, Processes Tab, Background Processes, it should be there on the list. It helps to click on the Name column heading to sort all the tasks in alphabetical order.

I think I have fixed this for the next release - hopefully I did not break anything else in the process.
