------- Additional Comments From mike@codeweavers.com 2006-19-01 23:06 ------- Likely to be a bug in Wine's msvcrt.dll. If you can program, try adding a ERR("%s\n", fmt); to the start of the sprintf function to see what kind of format string it's trying to use. If not, you can confirm that the bug is msvcrt by copying a windows version of that dll into the app's directory.
