Since late last week the Manipulate function results in Mathematica freezing then offering that it should abort. This happens with every Manipulate I try. For example Manipulate[a,{a,1,2}] or Manipulate[Plot[Sin[a*x],{x,0,2Pi}],{a,1,3}].
I am not aware certain when this problem began as this is the beginning of a semester. We did upgrade to 10.3.1.
That’s strange. It’s probably some weird glitch.
Please see this article, which fixes most problems like this:
Unfortunately resetting settings as described in the article has no effect. This is default behavior.
That’s strange. I would recommend contact Wolfram Technical Support then:
They will need to know a bit more about the problem and the computer you are seeing it on.
Technical Support has finally replied. While preparing the response for them, I stumbled on an even odder aspect of the error.
If I run a Manipulate command, then immediately try to use it, Mathematica freezes then gives an error asking I want to abort.
If I run a Manipulate command, then run some non-interactive command (e.g., 7+19), then access the Manipulate tools, everything works.
Try turning off the Suggestions Bar (it is one of the checkboxes in the Preferences dialog).
Thanks. Turning of Suggestions Bar worked.
I am able to reproduce the problem and suggested work-around in version 10.2.0. But if I simply wait 10 seconds after executing the Manipulate before interacting with it, the problem also goes away.
