WM missing icons - using 2 WM in TLB

Very interesting.. perhaps the condition headers the weather monitor plugin recognizes is hard-coded. All the sections that work were available in the default wunderground.ini provider file, and all the ones that don't work were not. Doesn't sound like a coincidence to me
If you would like to try changing the headers in you provider file, here's a list that will work:
[Sun]
[Clouds]
[Mix]
[PartlyCloudy]
[Lightning]
[Rain]
[Snow]
[Wind]

Alternately, you can use the right-click, change icon method I described previously to associate an icon with a specific weather condition anytime a non-recognized condition (no icon) is displayed. You only have to do it once, and the next time that weather condition comes up, the correct icon will be displayed.

I just realized another option that could solve your problems without having to wait for unrecognized conditions. What's going on behind the scenes when you use the right-click, change icon trick is that weather monitor creates a header in your current skin.ini file that references your current provider file (if there isn't one already). Then it adds a line equating the current condition (even if it has spaces) with the selected icon. The result is something like this:

Code:

[instaweather.ini]
Chance of Storms=rain2.png

It's a little bit more work, but you could take advantage of this syntax and add all the conditions from the unrecognized provider file headers and the icons that should represent them directly into the skin.ini file. Once this is done, it would probably be a good idea to delete the duplicate data from the provider file.

Let us kow if this helps.
