First use 'top' to check if it's Wing or the debug process that's
loading the CPU. It's possible it's both or that the debug process is
under load and Wing is getting stuck somehow waiting for data from it.
Is the debug process paused or at a breakpoint at the time? If so, it
may be introspection or other data inspection code that is getting hung
up on large arrays (but that's just a guess). We do try to identify
large values and not get stuck inspecting them but it's a rather
If it's Wing that is under load you can do this to get profile info
during a time period:
1) From the Edit menu do Command By Name and in the buffer at the bottom
of the window type internal-profile-start and hit enter
2) Do whatever hangs up
3) Using Command by Name again do internal-profile-stop
4) Submit a bug report from Wing's help menu w/ error log (this will
include the profile and other info)
That's a start. We can go from there to further diagnose it.
