Hi I am using 4.24 & it seems to be working. I have experienced the "Hang" you speak of with larger files, pits to lose work. I searched the cp for the repository that holds such files but I do not know where it is.
It seems that XP Pro with lots of memory seems to handle the math better than vista or win7? XP is what "Diamond cut"(Sound CO) recommends. . I have been striping down the bloat on the programs I use in Vista & that seems to help also running all the memory you can install seems to help a lot, I am kinda of sold on putting on as much ram as possible on any laps I run mow , world of difference.
I use The VST program for a noise program I have & it puts a "spike" (pretty wide spike) in at the beginning of the edited part sometimes. I use DC7 & 8 also but those who hack me seem to know that program too well & I cannot get anything done with it unless I am in the Faraday cage & then I only have battery time to work anything & that's only about an hour which is not much time for this type of endeavor. I paid for 8.00 worth of support & have not gotten that, rather frustrated with co's that don't respond, I guess the time difference is a problem but oh well. keep on going till ya can't go no more lol take care.
