Avast!Free 5.1.889 blocks saving projects in Delphi7

Subj can be reproduced on clean install WindowsXP SP3, Delphi7 and Avast!Free 5.1.889 in virtual machine for example. While saving file Projectname.dof Delphi says than project can’t be saved. With disabled filesystem monitor everything is ok.

Adding project source folder into global avast exlusions gives no result. Adding *.dof files into filesystem monitor exlusions gives no result too. Logs in avast are clean.

When delphi fails on saving, this file contains only first 20-30 symbols; in normal case it’s size is 3-5KB.
