Greetings Skwire, and many thanks for this great little application. There are many tray weather programs, but most of them are bulky, over shiny and over intrusive, so this one is just what I was looking for: tiny, simple, nice, informative and it gets the job done.
Though I found one conflict. I have excellent program "System Explorer" which has advanced tooltip that shows when pointing mouse over it's tray icon. Problem arises when "sWeather" refreshes weather data, it also triggers System Explorer's tooltip which then appears in random positions on my desktop and I have to click anywhere to make it go away. It happens every time sWeather refreshes its weather data so it's a little bit annoying.
Just to say that I'm using plain 32bit WinXP sp3.
I hope You can figure out how and why this incompatibility incurs and possibly fix it.
