A tip: I first built myself a version from svn (source) with the modification described in an earlier posting, but the applet wouldn't show up and when I selected it in the user panel I only got a popup with the same old error messages - even with the network off. Then I made a version which reads the magical string from /home/user/.omwrc, but I had the same problem. It turned out that I had to remove those short .xml files (with the original error report) from /home/apps/omweather/, after I did that it showed up in the UI when I selected it, and an update fixed everything. (And now I have a version with user-modifiable magic URL string, for future changes ) Unless there's something strange on my setup then this could be a problem also for those of you using the patched version that someone linked to above: If problems, remove the short .xml file(s) in /home/user/apps/omweather/ and try again (NB: Obviously you also need a patched omweather to begin with) EDIT: The problem I had (blocked as long as the old error-report .xml files were in place) could possibly be because the patched version I installed is based on 0.21, not 0.20)
