we're using the lastest version of GdPicture 9.
We're using TWAIN acquisition with different scanner with no problems.
But we have encountered some difficulties using the Canon Lide i220 scanner.
Usually, once you call the TwainAcquireToGdPictureImage method, the entire app freeze: and you must send keyboard input to unlock it!!
Can you help us?
The only thing we can suggest in such case is to try with the latest major release.
If the problem persists with it you will find here the procedure to send us need information for investigations: viewtopic.php?t=1486
