Either of below will disable Task Pane Manager launch on VFP startup:
Click on the Task Pane's Options, Select Task Pane Manager in the treeview and uncheck Open the Task Pane when Visual FoxPro starts
Go to Tools, Options, File Locations and clear Startup Program. Click on Set As Default to save changes.
In the RegEdit go to the HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\9.0\Options key and blank out Data for Value Name _STARTUP.
Add _STARTUP= to a config.fpw. Only VFP instance that uses this config.fpw will be affected.
