OSX... hi guys... duh... this is a bug. reaper versioning doesn't matter here. but anyway: 5.23. 64bit. & yes: OSX 10.11.6.
The last project i ran before exiting, I left a the mouse focused & selected upon a fx plugin (either AU DLS synth or sforzando, either can be buggy).
SO, when i re-run Reaper it hangs. Yes... reaper is set to auto load the last project, this is what i usually always want.
...Reaper is re-executed, the fx window is open, i don't get anytime to select another fx in the chain, to dodge the hang.
So... Can someone please provide me with a quick answer: as a method to change a setting in perhaps the config file to postpone the hang.
About your replies...
1) a Worst case reply scenario: is describing a way to change the config file so that when reaper re-opens... it leaves inserted ALL track fx plugins bypassed.
2) Second worst case reply scenario: leave all AUi VSTi instruments: bypassed.
3) Best case reply scenario: a setting to just leave the the 'offending instantiation plugin' offline. But because reaper hangs in this case, because of the problem, it won't and can't write what the problem is to a file & to then suggest the workaround in the re-opening error dialogue about 'The last time that this project opened it had dramas' guff.. ( is there even a reaper helper app that runs as a daemon to monitor reaper... a single failsafe.?)
Sarcasm: This certainly is a Very Good Way to LOSE projects :P
Sorry about my lack of communications skills. Not trying to be rude... just stating the wrongs as blatantly obvious to me.
