[OpenLayers-Users] strange transparency level changing

[BrainDrain]

Outside OL overlay images requested from MapServer has always the same
polygon opacity.
I dont think that it's a browser cache problem because I've observed the
same behaviour in 3 different browsers (overlay transparency decrease during
zoomin/panning - fact). I didn't see any working example of overlaying with
POLYGONS (from raster layer).  I suppose this issue related to images
loading order (server response time specific): for ex. initially (when
layers just were added) overlay layer loading is faster then base
