It's not really a bug... In earlier versions of Dosbox, if you tried to play the game in High Performance, the colors were constantly flicking and the game lagged a lot. This is because Dosbox wasn't able to support it. Now, Dosbox is able to, but I think it gets problem with color palettes. The only way to see exactly is to get an old PC (a very old one) that have Dos and try the High Performance to see what colors the skill bar and fonts are using.
So, I don't know really if it's Dosbox problem or Lemmings problem... or both! :winktounge:
I remember something that was used for the Atari ST. Atari ST could only support 16 colors, but in the game, you have way much colors. They used a technique that quickly switches colors so that it looks like there a much than 16 colors (I don't know the name of this technique). I think it's the same thing with "High Performance PCs" mode, but way much slower... If you take a screenshot with Print Screen, you get what you see on screen. If, however, you take a screenshot with Dosbox, well, you saw it by yourself!
Anyway, I must say that it's quite a bit "nice" to have alternate colors for skill bars, depending of the level style, but sometimes, like for the Holiday Lemmings style, it's not very nice...
You better took the one you just did with CTRL+F5 as if I remember correctly, the colors are always the same regardless of the level style.
