Our company forced to use an old 2009 version of Solidworks because of one of our clients that wont upgrade.

We used to run Windows-XP on our Solidworks workstations, but recently we bought two new workstations with Windows-7 in spite of knowing that Solidworks 2009 formally does not supports Windows-7.

Everything seems to run well except of very strange behavior of custom properties in drawings.

I have noticed of quote marks disappearance in custom property values like \$PRP:"SW-File Name" becoms \$PRP:SW-File Name and  \$PRP:"DrawnDate" becomes \$PRP:DrawnDate on new workstation.

Even if I manually add quote marks back they diapered when I close and open custom property window.

Is there any solution that do not evolve SolidWorks upgrade or Windows downgrade?
