The following code should show a button
and a text field. When I click the button, i should get
a system dialog allowing me to select a folder, and the
folder's file and pathname should then be displayed in
the text field.

Unfortunately, the performance is erratic!
If I click the button, then select a folder of the C drive, say C:\first,
and click "open", the textfield display C:\first as expected. But if I then
click the button again, and select, say, folder off the C:\first\second and
click "open", the textfield does not change, nor does it for any subsequent
clicks. However, if I select the desktop, it works as expected, and if I
select the C: drive again it also works.
To summarise, if i want to change the folder selection, I have to select the
C: drive once, then click again and select the subfolder I want, and if I
want to change the subfolder, I have to select the c: drive again, before I
can select the new subfolder.
Is this a bug, or am I doing something stupid? I am using V7 on Windows
Vista Home Premium.
Thanks in advance,
