Windows blue screen with integrated ProTool Project

Hi all,

I've got a S7/300 project with an OP7 connected. The ProTool program is integrated with the S7 project. When I open the PT-program using the link in the S7 project it gives me the famous 'Blue Screen' and shuts down of course. If I'm correct the message I get is
PAGE_FAULT_IN_UNPAGED_AREA
Opening this PT-program by starting the PT-software and selecting the project gives me no problems.
I've worked on it this morning as I allways do without any problems. After opening ProSave instead of ProTool the sh*t begun.

What, why and how to correct this is my question, not that I can't work anymore but I'm more curious if anyone else has seen it or if its just me?
(!!!Damn Siemens!!!)

Are your STEP7 and Protool updated to relatively late versions ?

When you open OP7 program from within Protool, do you do it from withing the project structure (integrated) or do you browse to the .pdb file (not integrated) ?
The problem may be that the "Protool integrated in STEP7" selection has been switched off.

Hi Jesper,
Thanks, but the problem is solved after a reboot of my PC, I should have thought about trying it first.
