My LW malfunctions in a strange way after apr. 30 min.
 

My LW at first works fine but after 20 - 30 minutes or so it slows down to a trickle.
My modem shows that it's sending something but I can't figure out what it is sending - there are no uploads.
Just restarting LW doesn't help. The only way to fix this (temporarily)
is to restore the defaults in preferences, and then restart.
I just installed LW 4.4.4. and the problem is still there.
Has anybody ever experienced that?
