Multiple instances of dragon.exe

Dont know if this is a bug or not, but thought I would start here.
Running Dragon 28.1.0.0.
Open Task Manager and have 11 instances of dragon.exe running with the following memory usage:
96,008k
28,632k
15,076k
25,484k
64,444k
25,196k
42,148k
66,684k
27,220k
37,200k
99,780k

Is this normal ? It happens every time.

This is a Webkit issue. The problem extends to any browser built on Webkit.

This is not an issue it is intended behavior. Read the links posted by captainsticks
