How do I flag an entry here as "Problem Solved"? Was looking for that when I posted my last entry but couldn't find it.

Hello Rosscoe68,

To the right of the post that solved the problem, you should see a button that says "Solved the problem" .....

It's a pain in the derrière; hence I filed a bug report some time ago :

(I noticed that a moderator marked your other thread as solved)
