#163 No thumbnails appear in layout grid after scanning with TWAIN
A critical defect has been introduced with this version of NAPS2. After I scan documents with TWAIN no thumbnail images appear in the NAPS2 layout grid. There were no error messages; for all intents and purposes the scan appears to have completed normally but the acquired image data is not getting back to NAPS2 from TWAIN.
I uninstalled v4.7.1 and reverted back to v4.5.1 and that version works fine.
I have exactly the same problem as Luke, (I am using a Canon DR-2580C) It works perfectly up to 4.6.1, but doesnt at all with 4.7.1. (Im also using TWAIN)
I havent had any errors in the errorlog with the normal 4.7.1, but now with the test version, i get the errors in the attached file.
I will try it as soon as i can get access to that specific type of scanner(its only the DR 2580C that causes problems, otherwise everything is perfectly fine). Sadly every single one of them is currently in use so i cant test it right nowPerfect! It works now.
Thanks a lot for your quick fix!
