I was having that same trouble, and others, a while back......it turned out that, mostly, I was so low on RAM that my machine was doing strange things............i twouldn't even run Firfox........
I did a bunch of defragging and stuff, at the kind and helpful advise from folks on the "tech advise......" thread.....
it bought me some time.......
then, I upgraded my RAM and now it's working just fine.........
things are hot and dry here....luckily, no big fires nearby like last year........
I had a great dark beer in Prague (Praha to Fishy......grin).
It was called Radagast
Saku, was another fav.
