[Jewel the Mystery]

hi people finally my computer works again =)
well, i have another problem with xwe:
everytime i want to test my wad in srb2 appears that error:

signal_harder(): segment violation

i have xwe (beta version) and when i want to rename the sprites to lowercases they stay capitals. what's wrong with it?

Go to View --> Options, then tick the box next to "Don't auto capitalize lump names".
