[mapguide-users] map refresh timeout

[Traian Stanev]

Try identifying which layer causes the slow down, by selectively turning off layers. Then see what's peculiar about the layer -- does it have a line style, or perhaps labeling. There is a known issue around that (layers with lots of labels at high zoom), which will be fixed very soon.
