Unable to open the Update Manager

[Ihor Romanyshyn]

Unable to open the Update Manager when there are updates and icon is displayed in the left pane. Icon simply does not respond to clicks. To update the program, you need to right-click on the icon and select "update all" or close the Update Manager and open it again manually to see a list of updates.
