tadvpolymenu version 10.7.4.1 Super flickery with double buffering disabled

We run our application on Terminal Server where Double Buffering isn't supported.

The tadvpolymenu has always been a little bit flickery on terminal server, but since updating to 10.7.4.1 the flicker is generating user complaints.

You can see the same effect running on a local system by setting Double Buffering=False.

Is there anything we can do to reduce the flicker?

What was the previous version of the component you were using as we have recently not done any changes to the TAdvPolyMenu component?
