Overcharging Battery causing operating issues?

I've been using my Macbook to extensive amounts over the past month or two Where its been charged or in the socket at 100% battery at almost all times. With increasing frequency i have been seeing a major decrease in how well its been able to process and perform generally. Recently I have been getting a lockup and freezing forcing me to terminate the computer using the power on/off button. For some strange reason, I decided about 30mins ago after a lock up to remove my adapter after which it instantly started to respond unlocking itself and returning to almost full function.

Could it be possible that overcharging the battery for this extended amount of time is effecting the performance of the computer and its cores? (i've noticed the performance dropping when the cores start to raise in how much they are working)

It is possible this is a coincidence but i thought it was worth asking anyway. I think i'm going to have to take it down to my local Mac store if it continues.

Spec:

Model Name: MacBook Pro
Model Identifier: MacBookPro4,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB

Many thanks,
