Only on one machine thusfar. However, the program will be distributed  
this week to about ten collaborators for feedback.
I will leave the timing routine in the program and ask them about  
their findings.

Real.

That is a hit!
After turning off my antivirus program (Norton Antivirus) on the Win  
machine, time droped dramatically!
Opening program after starting the computer, opening time DB:
- DB of 191 Meg: 8 seconds. On second opening of the program without  
turning off the computer:  2 seconds
- DB of 513 Meg: 9 seconds. On second opening of the program without  
turning off the computer:  2 seconds

So, without the antivirus program running, everything is normal and  
size doen't matter. I hope to learn from the testers what other  
antivirus programs do.
The diagnosis being mede, I do not know where to go from here. I can  
barily ask the students to turn off their antivirus program when  
using my program.
So what to do?

BTW, I have a antivirus program running on the Mac (VirusBarrier X5),  
but that doesn't seem to influence much.

At present, I have VStudio installed only on the Mac, the platform I  
develop on. I can download the Windows version and try it out if you  
think that may lead to a refined analysis of the problem..
Also, I'm very axious to learn what your thoughts are on "something  
else going wrong".. What would you look at?

Many thanks, Thorsten!
