Error for synchronous table.request in AW 2.6.1 for some IE installation

In AW 2.6.1
With IE version 11.0.9600.18793
Update 11.0.46 (KB4036568)

If you debug the tabla.request() code step by step it works but if your run through it you get an error:
"Error in the download of the requested resource"

It's very weird. Step by step does not rise error but running it does ?????????????

More info:

It is the second time you do the sync table.request that fails unless you go through it step by step.

The first time it runs through it no problem

And the same thing with some asynchronous calls
