Hello
Can't believe I hadn' t played this game until now...
I am not sure how active this forum is (last thread is a year ago!) but I was hoping someone would answer rather than me having to use a walkthrough.
I am in the attic and using the screwdriver to open the suitcase- very unsuccessfully.
Is there a specific pattern? I have tried moving it around but the cursor makes any movement limited.

Any help would be much appreciated...
