I did the same automatic upgrade (as d&ss1) to 1.6.0.31 last night and now my system is so slow it's unusable (it's my work PC), so now I'm in a panic. The worst is my email client software, Sea-Monkey, it now takes forever just to move from email to email.

1) What can I do to get the original speed back? Are there adjustments or tweaks I can do to stop the slowdown?
2) Or should I uninstall 1.6 and reinstall 1.5? Would this be the safest choice?
3) Should I have uninstalled 1.5 before I installed 1.6? (The automatic process did not present this as a choice)

Thanks!!!
