Avast vs Miranda-IM

Hello!
I have problem with Avast Home Edition and Miranda with popup interoperability plugin. When any popup is appearing, useage of CPU of ashserv.exe process is raising up to 90% and system is hanging for a while. This situation have started with newest version of avast program (4.5.523). I’m WinXP with SP1 user.
