How to disable flashing VirtuaWin systray icon? Window is not responding

I have to run an application which is not responding so ViruaWin isn't able to manage it. (There is a "1 window not responding" tooltip on its systray icon.) Because of the hanging VirtuaWin flashes its systray icon which is really disturbing. I'd like to disable the flashing.

I've read the Window not responding? forum topic and I've also tried to create a new Window Rule with the class name of the hanging application but it doesn't work, the icon is still flashing.

The hanging application from the WinList module:

The created Window Rule:

How can I disable the flashing (without hiding the systray icon)?

So this how you deal with it...

First you need to find problematic windows:

1. Open VW setup.
2. Go to Modules -> WinList -> use Configure button.
3. Right click on WinList window title bar and choose Stop Managing item.
4. Switch between desktops until you get a blinking tray icon.
5. Refresh the list and sort by S column. You should have some windows with "H" in S coulmn (like on the image below).
6. Take note of the Class of the hanging window(s).

Now you need to change window rules:

1. From tray icon menu choose Window Rules item.
2. Type in Class name (or Window name) and choose Never manage windows of this type option.
3. Click Add button to add the rule. And OK to save rules.
4. This is important - the rule will NOT be active until you restart VW. The quickest way is to Exit VirtuaWin and run it again. Reapply Rules might work too.

For Windows 10 I added tooltips_class32 and Windows.UI.Core.*. You might also want to add similar rule for ApplicationFrameWindow class to get rid of windows with empty title in application lists.

For Vista I'm guessing that would be TscShellContainerClass.

It should be fixed in v4.5. However, personally I would hide the icon and use the KvasdoPager module instead. The taskbar is still neat, but I still can manage the apps I don't need now.
