The IE9 browser is recommending that user's disable plugins.
See attached screen capture from IE9. The bar at the bottom appears first, and upon clicking on the "Choose add-ons" button the dialog appears listing any plugin that takes longer than .2 seconds to startup.
Fix has been implemented as described in the comment section.
Some performance results (load time reported by IE in s.)
On XP / IE8:
no fix 0.70 with fix 0.12
On win7 / IE9:
no fix 0.06 with fix 0.01
Note that the code paths for XP is different from win7/vista, that's why the differences in load times for different windows.
