Troubleshooting for PDF Professional
The page keeps scrolling down whenever I click with the Hand tool
This behavior may be set. Click again to stop the scrolling. If you do not like this, go to Edit > Preferences > General > Miscellaneous and change the behavior. Change Scroll down to Do nothing or Page down (a click moves the display half a page down).
I have unexpected behavior when I select objects
Be sure you are using the 
Select Object tool in the Standard Toolbar. Use Ctrl with this tool to select multiple objects (for instance to line them up).
The 
Select Area tool in the Standard Toolbar does not select objects but screen areas – for instance to copy them as image.
Touched-up text becomes colored and unreadable
You may have turned on the fill-stroke feature without realizing it, or gave unsuitable values. Click a text and choose Properties in the shortcut menu. In the Touchup Properties dialog box select the Text tab and select No color for Stroke color. To make this feature work well, the font point size must be at least 30 times bigger than Stroke Width.
Bates stamps are not applied
It is possible to specify a page range for stamping; if you specify an invalid range no stamps are applied, even though the Bates stamping is reported as done. Modify or remove the page range.
I cannot select multiple PDF documents to search them
To search multiple files, group them into a portfolio; then you can search all or selected files in the portfolio. Alternatively, copy or move the files to a separate folder and perform a folder search.
I cannot select a folder for a folder search
Select a drive then choose Browse at the bottom of the drive list. You may have to scroll down to do this.
I cannot deselect a radio button form control
Radio buttons work only in groups. To make a group, place second and following radio buttons with the same control name as the first one – do this in the control’s Properties dialog box. Then the buttons will work; only one per group can be selected.
Creating tagged PDF files
Tagging is not provided as a separate setting when printing to PDF; access it through profiles in the Create Assistant. There is a pre-defined profile Tagged PDF, but you can specify tagging within any other profile. Use Tags panel or the Tools menu in PDF Professional to tag an existing PDF file. Be aware that tagging is a resource-intensive operation that may take several minutes. Use Esc to cancel a tagging operation.
