Uses list slow

Hi,

first of all thanks for the great product.
I have a problem with Delphi 2007, IDE Wizards 0.9.6.569 Build 2010.05.01. I have a big project with 1200 forms/units. The uses list is slow, around 30 secs, where as the default uses list takes 2 secs to open. I suspect loading filesizes takes long time

Any ideas?

Best regards
