Yea - there's something weird going with graphics interaction with versions 6.3 on... I have the opposite problem where certain projects will not close and it hangs at "Initializing" - even with no plug ins loaded. When it does this the CPU goes up considerably.
Thing that's strange is that if I zoom the TCP all the way out, the CPU utilization drops and the same project will now close without hanging at "Initializing"
6.23 does no behave this way regardless of the zoom level of the TCP

Using Systernals Procmon, tracing the reaper.exe shows this.
At the end of the one that does NOT close you can see that Reaper never gets past IRP_MJ_CLOSE on the Reaper.ini.
58:34.1 reaper.exe 10780 IRP_MJ_CLEANUP
58:34.1 reaper.exe 10780 IRP_MJ_CLOSE
58:35.0 reaper.exe 10780 Process Profiling
58:36.0 reaper.exe 10780 Process Profiling
58:37.0 reaper.exe 10780 Process Profiling
58:38.0 reaper.exe 10780 Process Profiling - and on and on. Never completes...
The one that DOES close - which is the same file, just with the TCP zoomed out and scrolled to the bottom of the project, goes all the way through to:

Something weird going on here.
