There's always one isn't there! That small thing that frustrates you!! I'm trying to remove a wardrobe facing board (a cover that was masking the top of the sliding doors. All four screws were seriously embedded and about an inch from the base of the hole. I've got 3 and just can't shift the last one. Is this a brute strength thing or is there another trick to keep the screwdriver blade in the slot as I push up? It doesn't matter if I disfigure the board. Any suggestions? Photos hard to get.

Cut away some wood to try and get better access
