Matlab freezes on startup

Hello all,

I'm running:

• Windows Server 2012 R2 Standard 64-bit
• MATLAB R2014b

Sometimes when I start up MATLAB, nothing appears on screen. Using Process Explorer, I can find the stack trace for all threads launched by MATLAB, but I don't know how to interpret them to resolve this issue. Before I list the threads, I want to note that this issue occurs for all additional MATLAB instances I open after this one, as well as any I open if I log out and log back in; only restarting resolves this (for a while...).

FYI none of these work or make any difference in the stack traces:

• Deleting my preferences in C:\Users\***\AppData\Roaming\MathWorks\MATLAB
• -nojvm
• -nodesktop

Process Explorer -> MATLAB.exe -> Properties... -> Threads:
