Authentication data not clearing using Tortoise 1.4.0 onWindows XP

I think I've found a bug when trying to clear authentication data when using
Tortoise 1.4.0 on windows xp:
 
I selected TortoiseSVN...Settings from windows explorer, opened the 'Saved
Data' tab and clicked the 'Clear' button against 'Authentication Data'. The
button is now greyed out, but I am not prompted for new credentials when
performing an update or commit. (The respository does not allow anonymous
access and the changesets I commit have my name against them).
