Menu Bar is waiting for a FolderInstance (in EDT), which is waiting for a FolderList, which is waiting for a logger (UIHandler), which needs to be flushed before publishing the log record. Flushing of logger data via FileChannelImpl takes quite long.

It seems that the hard drive was under heavy load.
Closing. Please reopen if you can reproduce the slowness.

Thank you for reporting.
