------- Additional Comments From saulius.krasuckas@elst.vtu.lt 2004-15-07 03:07 ------- Stuart, if you know exact two dates (20040309 and 20040408) between which the regression has been introduced and if you still have Excel installed, you are given a chance to do a cvs-regression testing.
yes, you would need to learn at least two of the "cvs" commands ("cvs login" and "cvs update -D ...") and to do some jumping: dividing and shortening time intervals and compiling your wine/ tree multiple times.
but hey, this way you would help winehq bug database, winehq community (and even yourself if the regressive patch you will find gets fixed):
