I just tried the Spark client and ran into the following possible bug. I added the IM Gateway plugin and then added login information for AIM in the Spark client. It worked great. My buddy list and groups downloaded and displayed as expected. I proceeded to remove the account. The active buddy groups dissappeared but the ‘‘offline’’ group and it’'s listed users did not. I closed Spark and restarted it but to no avail. The ‘‘offline’’ group still appears.
