disable headset button

[Guest Diseased]

I'm using Topaz with wm 6.5 (original). The problem is when i'm using the normal HTC headset with button i've got no problems. When i'm using a converter cable to 3.5mm & attach a normal headset from like sennheiser it automatically calls (sometimes each minute, sometimes like 10 minutes nothing) the last dialed number and hanging up directly after it.

It kinda looks like i'm pressing the headset button, but i don't even have a button to press on.

Now my question is that: "is it possible to disable that hotkey/headset button, somewhere in the registry or with some app?"
