Preferences dialog, and a couple of other items

Running Win XP and Amaya 10.1 pre 4. I uninstalled
a 10.0 install prior to installing 10.1 pre4.

I have the 'Panel bar position' on the left and if I call up the
preferences dialog it shows the 'Panel bar position' as being 'Align
left'. The 'apply' button is enabled despite the fact I've not changed
anything. If I click 'apply' my Panel bar shifts to the right and I get
a 'Confirm' dialog that says my changes(???) won't be applied til I
restart Amaya. The 'Panel bar position' is
still showing as 'Align left' in the dialog....

The above 'Confirm' dialog appears to be system modal and
not just modal to the preferences dialog. As I'm typing this email the
dialog is in front of my email programs compose window or any other
window on my desktop.

When I double click on a link I get the file opened and it replaces the
old file rather than being in a new tab. I can see that this is the
behaviour I'd expect according to the 'Browsing' help page, but I've
got Preferences/Browsing/Opening Location/In new tab set. The help on 'Browsing preferences' doesn't
explain what 'In new tab' actually does
when it is set, but I'd assumed it was supposed to modify the link
opening behaviour...
