Ash, the problem as far as I can tell is the way Destinator shows the sat count. When there is no signal Dest shows it as a single 0. This is why there is only one instance of the icon showing on the desktop. In the car when FD first starts up the left hand sat icon shows 1 bar and tells me there are no sats available. As soon as the gps gets a lock the second icon appears to the right of the other one with more bars depending on the sat count. I rarely get over 9 sat locks so it can't be what Enforcer says but I understand what he means. Grave pretty much sussed it in his post but I didn't understand it at first.
I tried editing the GPS font and cut the number 0 out of it all together. I figured seeing as I don't get 10 sats locked it wouldn't be a big deal. However, Dest still wants to display something for a 0 and it ended up displaying the outside edges of a box.
It seems to me the only way to get one icon to show is to configure Dest to display sat counts as a single figure like the speed rather than the 0, 01, 02 etc. That way any figure from 0-9 would be reflected as one graphic. What happens when it gets to 10+ probaly wouldn't bother me anyway.
One other thing I noticed was that the 3 icons to the left of the sat icons disappear when changing from day to night modes and vice versa. Clicking on the window and choosing each item from the menu pops them back but obviously you have to click them twice to get back to the original settings. Seems they don't get refreshed when changing night and day mode.
The sat thing is a limitation of Destinator which is a shame as the graphic icon is a great idea. Still a good skin though mate
