After scanning pages of a paper document, I go to save the scan to a PDF file, but Acrobat pops up a blank dialog box that won't let me pick a folder or create a file name to save the document in a Windows folder. This has been happening since an upgrade about 2 weeks ago. HOWEVER, if I scan one page of a simple, letter-size B&W document, it does allow saving the document, after which I can scan and save any number of additional pages. BUT, if I scan one page of a letter-size color document (even at 100 dpi), Acrobat won't let me save even the first page. Is Acrobat choking on the size of the image, allowing the smaller B&W page scan to work but not the larger color scan? I'm running Win11 with all updates and 32 gigs of RAM, if that helps.
