you might be able to fix this by editing the project's xosm file
<ProcessInterface id="ScreenTransferFunction" workspace="Workspace04" trackView="true">
<geometry visible="true" left="2560" top="861" width="1991" height="146" status="normal"/>
if you were to set left/top to something smaller than what you find in your xosm file, maybe it would be visible. however, this might not work because of the project checksum / sealed project code. not sure if it would entirely refuse to load an edited project or give you the option to continue. i guess to get around that you could save the project with "sealed" turned off and then edit the xosm file. above all i would make a backup copy of the original xosm file before you start making changes, in case PI refuses to load the hacked file.
