I'm using windows XP pro 32 bit ver, running the game full screen (or sometimes windowed) at 1024x768 resolution, same as my desktop which is set at 32 bit color.
Running gal civ 2 ver 1.0X.010 from stardock.
Sometimes when removing things (by clicking on it in the installed parts list) on a ship (especially when doing an upgrade) they stay in the list of parts, although they can not be clicked on anymore. Often if you try to remove another piece by selecting it form the list, the first part gets put back in. Finding and then clicking a part manually on the 3d ship screen, then clicking remove works fine though. No error message shows with this bug.
If more detail is needed to reproduce this I can mention step by step info and can provide save games or screenshots.
Note that the post immediately below this contains an additional bug that seems to be differant (although perhaps related), with ship designing and removing parts and getting an error message.
Edit: After the patch, this bug is still present, though in a stranger form. When you do an upgrade, and remove a jewelry component (engines, etc, are removed after clicking upgrade which was a change introduced by a patch), then click the component list again, often the original engines and stuff will be put BACK into the upgraded design, as well as that jewelry component that was just removed. I suppose that quirk could be used by people who want everything present when they click on upgrade, but its a bit difficult to selectivly remove components with the design screen behaving this way.
