There are few things we can do to try to track down the cause of the issue:

1) Run the following command in the status window to turn off a number of features:

//treebar off | switchbar off | ebeeps off | flood off | remote off | notify off | ignore off | aop off | avoice off | protect off

2) Open the Address Book/Highlight dialog and turn off highlighting.

3) Open the Options/Connect/Options/Ports dialog and turn off all UPnP options.

4) Open the Options/IRC/Logging/Options dialog and turn off all logging.

If you do the above, does that help at all?

If it does not, are you using anti-virus or security software? If you disable/unload it, does that help?
