Should EMDK be updated on WinCe devices?

I investigate an issue related to the scanner on a MC65 device. When the scanner is enabled (throught the use of the EMDK librairy), the whole system gets kind of slow and unstable.

 

I was wondering if maybe the EMDK version on the device had to be updated.

 

From what the 'CheckAPI' utility tells me, it have version 6.00 of ScnAPI32.dll. How can I know this is the most recent version?
