Hi,
I'm using latest version (from may 2011) and noticed strange problem.
When I have plugin wxSU installed and !trace_console.rb, while Sketchup is running - no problems, and CPU usage is as expected.
When I try to exit Sketchup,SU window is closed but Sketchup.exe process is not finished, and it uses maximal CPU load (when checked in TaskManager).
##########
If only one of these 2 plugins wxSU and !trace_console.rb is installed Sketchup process is ended without problems.
It seems that writing to text file is blocked for some reason, and trace file can't be closed.
I'm using SU 7.1 and 8, on Windows 7.
