[R-SIG-Mac] Help! R Freezes When Clicking on the Icons

[Scott Novogoratz]

While it started as an occasional freeze, I now can no longer get the R.app Source Script icon to perform.  Each time I click it, I get the spinning pinwheel and need to Force Quit R.

Here’s my sessionInfo():
> sessionInfo()
R version 3.3.1 Patched (2016-06-28 r70858)
Platform: x86_64-apple-darwin13.4.0 (64-bit)
Running under: OS X El Capitan (10.11.5)

locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods  
[7] base     

loaded via a namespace (and not attached):
[1] zoo_1.7-13      xts_0.9-7       grid_3.3.1      IBrokers_0.9-12
[5] lattice_0.20-33

Here’s my About R info:


With help from David Winsemius, here’s what I tried so far:
	1. Deleting the .Rdata and the .Rapp.history files from my working directory
	2. Reinstalling R
	3. Setting my working directory on startup

Additionally, I have 3 Macs and all of them are having the same problem.

Does anyone have any ideas on fixing this problem?

Thank you for your suggestions.
