# Unexpected context change

I have a strange problem with Mathematica (10.1.0 for Microsoft Windows (64-bit) (March 24, 2015)). Namely when I evaluate expression

assumptions = {0 < t1 < t2, 0 < t3}


the context is automatically switched to

ParallelConcurrencyPrivate 


or just

Parallel


Before:

In[1] $Context$ContextPath

Out[1] "Global"
Out[2] {"PacletManager", "System", "Global"}


After:

In[1] $Context$ContextPath

Out[1] "Parallel"
Out[2] {"ParallelVirtualShared", "ParallelStatus",
"ParallelPalette","ParallelParallel", "ParallelKernels",
"ParallelProtected", "ParallelDeveloper", "Parallel", "System"}
`

Does anybody has any explanation for this behavior? Any suggestion is welcome.

• I don't have 10.1 installed anymore, but I would try turning off the suggestions bar (and perhaps restarting the front end). Oct 31 '17 at 18:21
• This problem is similar to 84515, I think it has been improved in later versions. Oct 31 '17 at 22:31
• @Szabolcs It's my work computer. I'll try tomorrow and update. As a matter of fact, it all started when I changed context to notebook (via menu). Though I reversed the context back to global, the problem persisted and actually it extended to any notebook persisting over sessions. Oct 31 '17 at 22:36
• @Szabolcs In light of these new findings, should this be marked as a bug? Oct 31 '17 at 22:51
