Summary: file dialog to select attchments slows down for many
                    files
           Product: Wine
           Version: 1.1.12
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I use wine + Lotus Notes 6.5.5 at a stable Gentoo system.

If I try to attach *many* files to a document (few dozends) then it takes a
*loong* time (1 minute and longer) and the system cpu goes up to 100% before
all selected files are marked and the file dialog comes back and the files are
attached.

OTOH selecting only few files within the file dialog isn't the problem, but if
I have to scroll to the left/right within the file dialog to mark to last/last
file to be attached it needs time until this is done.

Furthermore the time seems to be an O(n) funktion, meaning that if the file
count is doubled, it seems to need 4x times longer and so on.
