I am having trouble with the -initialdir option of getOpenFile.
The situation was that is was working on my system but not at one of my user’s.
I have written a test application where I used the code for getOpenFile from the proper application.
This is below.
I now have the problem that the –initialdir option does not work in the test code!
In the test you use the first button to select a directory.
This is shown in the entry box and can be altered.
You then use the second button to try getOpenFile.
If the directory cannot be found you get an error message.
In getOpenFile you can see what directory is acting as the ‘start’ directory.
I would be grateful if anyone can tell me why this test code does not go to the correct directory and/or why I find different behaviour on different systems

# test-dir
# this is to test the initialdir option for the file browser

use strict "vars";

# say to use Tk module

# create main window

$mw = MainWindow->new;

$mw->Button(-text => "Select Directory", -command => \&setdir_cb)->gri
+d(-row=>0, -column=>0);

$add2_entry = $mw->Entry(-width => 60) ->grid(-row=>1, -column=>1);

$add2_entry->configure( -textvariable => $dir_full);
