           Summary: file open dialog: slow when selecting many files
           Product: Wine
           Version: 1.3.17
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: pa78 at gmx.net


The bug:
The more files I select in the file open diaolg the longer it takes until the
files are actually selected and I can click the open button.
This bug is not about the load time of the program but the time the files get
selected in the file open dialog.

Hints to reproduce:
Selecting one file in the dialog window happen instantly.
Pressing shift and selecting 3 files also is very fast.
Pressing shift and selecting 10 files takes up to 1 second.
Pressing shift and selecting 30 files already takes 10 seconds.
Pressing shift and selecting 50 files already takes 40 seconds.
Pressing shift and selecting 100 files already takes 270 seconds (equals 4:30
min).
As you can see times are raising nearly exponential.
In Windows/Gnome/Kde/... it doesn't matter how many files are
selected/deselected. It takes always the same time.

Additional notes:
My cpu is a 3 year old dualcore 1.86 ghz. If you can't reproduce this times
because your machine is much faster just select more files because time is
raising nearly exponential.

This is an old bug (probably pre wine 1.0) and still (wine 1.3.17) very
annoying to me because sometimes I have to open a few hundret files. I think
this was never implemented well. Just so far that it is possible to open one or
a few files.
