Another small error in the CVS version (again I think since 0.2.8) which I so far lack the knowledge to fix, this time in the GUIINV.py file.
File "./GUIScripts/bg1/GUIINV.py", line 153, in OpenInventoryWindow
File "./GUIScripts/bg1/GUIINV.py", line 233, in UpdateInventoryWindow
UpdateSlot (pc, i)
File "./GUIScripts/bg1/GUIINV.py", line 416, in UpdateSlot
GemRB.SetButtonBAM (Window, Button, SlotType["ResRef"],0,0)
AttributeError: SetButtonBAM(WindowIndex, ControlIndex, BAMResRef, CycleIndex, FrameIndex, col1)
(as a side note, the red syntax error text telling me this continued as red after the error, so all subsequent messages were also red)
As I say, I compared with other GUIScripts, but couldn't find anything to help me out.
