Hello, I've been working on the Bugzilla problem #47641, "Treeview Expand using option TVE_COLLAPSE|TVE_COLLAPSERESET causes crash" https://bugs.winehq.org/show_bug.cgi?id=47641
I applied the patch supplied there that was created by Alistair Leslie-Hughes. I came up with a fix that works as far as I can tell. I explain what I did at the Bugzilla link. I've posted the patch fix to this list under the title: "[PATCH] comctl32: Fix Treeview Expand using TVE_COLLAPSE|TVE_COLLAPSERESET" Thanks!...John Alway
