Can't resize Access 2007 Navigation Pane
Hit F11, to close the pane, then drag it out.
It is an infuriating problem!
Just ran into this problem with Access 2010 database saved in Access 2002 - 2003 format. Click F11 to collapse the Navigation Pane. Then select the edge of the collapsed navigation pane and drag to the right.
Just had this Navigation Pane problem in Access 2010... infuriating is an understatement. Lost an hour trying to figure it out... lost a form that wouldn't save in the process.
With a database open, goto: File/Options/Current Database/Navigation Options{button}/ De-select the "Show Search Bar".
Should be able to open the Database and expand the navigation pane, now.
Thanks.
