When selecting a location above the arctic circle (66d33'38"N) the day/night indication (background color) in the Altitude vs. Time window renders completely wrong.
To replicate the error:
* Open the Altitude vs. Time window.
* Add the Sun to the list, to have as a refference.
* Select an apropriate location, such as Kiruna, Sweden.
* Check the plot at midwinter, midsummer and around the middle of spring and fall.
My test results for Kurina: (ISO dates)
2009-01-01 Looks OK, is all black as it should be
2009-04-01 Wrong: Is black to the left and blue to the right. Should be blach in the middle and blue at the edges.
2009-07-01 Wrong: Is all black, should be all blue.
2009-10-01 Wrong: same error as 2009-04-01
I tested other locations with similar results
(Thule, Greenland; Point Hope, Alaska, USA)
I also tested a location south of 66d33'38"S with similar result.
Thanks for the bug report. This seems like a hard one.
I'm finding the behaviour rather sporadic. Are you able to consistently reproduce the problems? I find it behaving correctly at times (especially when I step through, so it looks like one of these: http://en.wikipedia.org/wiki/Heisenbug##Heisenbug :-D). It would be nice if we could find out under what conditions it works and under what it does not.
Prakash said he'd do something about this.
