Probably by looking closely at the implementation of the PM callouts for the driver, but I couldn't find a pattern that would be easy to recognize. Maybe I didn't look close enough ;-) I concur that removing the check would be a better approach if it's clear that it's just done "out of habit". Actually, the real problem is to find the drivers that need to have the check in, add/fix it for them, and remove it for all others. Unfortunately, all I'm currently able to do is finding the parts that are inconsistent. Tobias
