Runtime Error 401

[I][edited from support email][/I]

During part of the experiment, the screen does a funny thing
and shuts down the entire experiment, mid-way. The screen reads the following:

The time allowed for this section of the study is over.

Run-time Error '401'
Can't show non-modal form when modal form is displayed.

Any clue?

I notice you have a word document timed within the que file [I]and[/I] the que file timed within the exp file. Try removing the duration (d) parameter from the parameters in your .exp file so you’re not timing it twice and see if that helps.
