When I have more than one PDF file open and insert a text box, or have an existing text box, and try to edit either, the text properties tool bar turns off in that PDF and opens in the other PDF such that the font properties of the text box in the current PDF cannot be edited. If switch to second PDF where text property toolbar is showing, then click on text box to edit, tool bar turns off in that document and opens in other document. No method to turn tool bar back on/open. Any way to fix? Adobe Standard 9.4, Windows XP.
Are you using Ctrl E to bring up the properties toolbar? Have you tried docking the toolbar with your other tools at the top of the screen so it is always available, then quitting & re-launching Acrobat? I haven't seen this issue.
