If you find that your Find / Change window is not appearing or displaying properly, you can try “resetting” the Window and see if that resolves the issue for you. First, you will need to close out of ProjectPAK. Next, access the Registry Editor by going to Start | Run and type in regedit. If you don’t see the Run open, then use the search bar in the Start menu and type regedit.  Navigate to HKEY_CURRENT_USER | Software | TradeSoft | ProjectPAK. Delete the following folders please:

FindChangeItemsDialog

FindChangeItemsView

Close out of the Registry Editor and that should “reset” the Find/Change window for you.
