This happens now and then if you are using a 24-bit display. You can tell if that's the case by looking at the output of "xdpyinfo" in a terminal window. The script that generates the weather images at the server seems to have some kind of bug where it occasionally changes the color value of the background pixels from 0x000000 to 0x010101 and back without warning. Xastir can handle at most one transparent color, and that color is coded into the WMSRadar.geo file as a hex number. When the user is using a 16-bit display, xastir does some manipulation of the pixel values to squash them down into sixteen bits before it checks whether the color is supposed to be transparent --- and in doing so the difference between 0x000000 and 0x010101 is obliterated, so this bug is invisible to anyone running a 16-bit display. But users of 24-bit displays get to see the effect you're seeing. Some folks here will tell you to run a 16-bit X server because that's the most supported color depth in Xastir, but I find that suggestion unhelpful because Xastir isn't the only thing I use my X display for, and I prefer 24-bit color for my other applications. Until Gerry can find the source of the seemingly random changes in background color produced by the weather radar script, the best you can do is to edit the WMSRadar.geo file to change the TRANSPARENT value. If it's 0x010101 then change it to 0x000000 (or vice-versa). It might fix the map. You will probably have to change it back a day or two later, though. This has been going on for quite some time --- at least a year, maybe more. Gerry has never been able to locate the source of the problem. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 AHTB#1 http://kevan.org/brain.cgi?DDTNM "And, isn't sanity really just a one-trick pony anyway?
