Text Disappears from Tool Tip

First of all, I love the new tray icon skin - it’s probably my favorite improvement in 5.6. Being a W2K user, it enables me to see all the data I want in the tool tip area - previously impossible.

Unfortunately, on a semi-regular basis, all the text data gets erased from the tooltip - I just see the blue background, and the current weather icon. I have to stop and re-start Weather Watcher to get the text data back into the tool tip.

Is this something that can be fixed? Is there more data I can provide that would be useful?
