Sky/star oddities

[Danth]

In "fog" type zones (such as greater faydark or great divide) I can see Titanium's default stars, especially if I look directly up. In addition the sky in open zones (like east commonlands) is not clouding over when it rains in game, leaving a bare sky again with those same stars visible. This same effect is observed whether I install P99's custom sky files by dragging the new sky files into the original Titanium "sky" folder or by replacing the folder entirely. Same effect/visible stars occurs on both my PC and the wife's. Full re-installation did not resolve it. Changing in-game option from complex to simple sky does not resolve it.

Open to suggestions, unless it's a known issue with no resolution.
