I am using the MBS TWAIN plugin and it works very well so far. I stumbled upon a problem I can not solve. It can be reproduced when using the „Twain.rbp“ example project which comes with the plugin. When pushing then „Aquire without GUI“-button and there is no paper in the feeder of the scanner then a messagedialog appears. The messagedialog tells me, that there is no paper in the feeder and I can click „OK“ to retry or „Cancel“ to close the messagedialog. When I click the „Cancel“-button and the messagedialog closes, then it is not longer possible to scan images. The „Aquire without GUI“-button does nothing after that. What should I do to make scanning possible, even if there was no paper in the feeder and the user closed the messagedialog by clicking the cancel/abort button?
Thanks in advance,
