When Validator runs sometimes it puts two different items into the system tray. The problem is, you can't tell them apart. I would like it if you made them have unique wording in the left hand characters or different colours so you could easily select the one you want.
Do you mean taskbar buttons? CSE HTML Validator doesn't use the system tray.
Can you be more specific about what is confusing? I know there can be a taskbar button with a blue "H" for the editor and one with a red "H" for the Batch Wizard on the taskbar at the same time, but you can tell the difference between those by color.
