Chrome loading pages on custom ESS

We have a customization within pactions.htm that in V9 was not a problem.  The customization was 3 DME with functions that called each other.  In V10 portal, if we run this in chrome only the functions seem to run in one thread and the rest of the program in one of more other threads.  As a result the loading of internal tables that are needed for the rest of the program are not available when needed.  The only thing that we have found that fixes this is to actually put in an Alert statement.  A wait process does not seem to have any impact.  Has anyone experienced something similar and found a work around.
