Repository Browser / Properties - removing / importing issues

Hi,

I was going through the browser's Properties dialog functionality, some
things that probably need fixing;

1) Select any existing property and click Remove => the property gets
removed without a chance to provide a log message (or possibly to cancel
the op)

2) In an initially empty Properties dialog, click Import and pick a
priorly exported svnprops file => The dialog a) does not ask for log
message and b) it does not display any of the imported properties ...
<=> re-opening the dialog displays the expected content

3) Should there be a check against adding duplicate properties? As of
now, adding a pre-existing property seems to convert to a 'edit
property' operation

A nuisance in the repository browser itself, quite often the selected
tree node on the left view seems to change upon opening/closing a dialog
=> one has to re-check things etc ...
For example, consider right-clicking on a 'tags' folder, selecting "Copy
to ...", at the time the "Copy to ..." dialog is up (displaying the
correct path), the selected tree node in the left view has changed to
'trunk' folder.
