lock display while in call

[rudolfv]

Hi,

I'm using a HD2 running Energy ROM. I like the HD2 very much but i have a problem with it.

During a call the screen is suposed to go black (lightsensor), i don't know why but sometimes it seems to fail. It might be my ear, long hair, being to fast or whatever causing this...
This might not be a big problem but the anoying thing is several times i seem to touch the topbar and Comm Manager get's started, next thing i do during a call is enabling Airplane mode or disable my phone.
Resulting in a disconnected call......

Is there a way to manual lock the screen somehow? Or does anybody have a idea what i could do? Any good tool for this?

Maybe a detail, i'm lefthanded...... Could this have to do anything with my problem?

Thanks, Rudolf
