Hello, Kevin.

Assuming, this is multithreaded application, it might have synchronization problems.
In this case you could add the GuiLock variable in the beginning of your updating function (or method):

App::OnUpdateData()
{
	GuiLock __;
	// Ctrls updating below
}

Also, I've noticed as I'm writing to the array control so quickly and such, it seems to be "flickering" quite a bit. Is this normal? Is there a better way to set the data? It seems that it is refreshing the entire table each time for some reason.

There is some discussed topic about this:
"howto best Ctrl Refresh handling w/ MT & very frequent refreshes".
