Attached is an Application Compatibility Toolkit fix that stops FolderSize from locking up Google Chrome during Save As, etc. The fix works by preventing chrome.exe from loading FolderSizeColumn.dll. Install by running the following command line: sdbinst "FolderSize Fix for Google Chrome.sdb"
To modify the .sdb file you will have to install the latest version of the Application Compatibility Toolkit from http://go.microsoft.com/fwlink/?LinkId=121777, then open it in Compatibility Administrator. This step is not necessary to install the fix because sdbinst is part of Windows.
