--- Comment #7 from David Hall (gringer) winehq@gringer.dis.org.nz 2007-10-06 21:56:26 --- Created an attachment (id=8425) --> (http://bugs.winehq.org/attachment.cgi?id=8425) C&C log, timestamps added in wine_nt_to_unix_file_name (via WARN, time(NULL))
I added 5 timestamp commands (via the WARN function) throughout the wine_nt_to_unix_file_name method (1 second resolution), and the log of that suggests to me that the blocking is not happening during the search for files (so this bug should probably be reassigned to a different section). I'll try adding more debug flags via export to get an idea of the dll calls that are made around that time).
note: I've chopped off the top and bottom of the log to only concentrate on the part where I was "clicking on OK".
