June 14-2012: See this blog post re the same error in relation to Adobe Flash & Web Browser issues.
There is presently an incompatibility between Dragon and Adobe Reader X for some individuals. When you are copying and pasting by voice or using the Dictation Box, you may receive the Dragon error, “SendKeys cancelled”. This is due to interference from Adobe Reader X.
- Ensure you are using the latest version of Adobe Reader X (you may need to update the software). Click on Help> Check for Updates within Adobe Reader. If the update does not repair this issue, we suggest:
- Revert back to Adobe Reader 9 (with its latest updates applied) until the next update of Adobe Reader.
This is a rather benign bug, but may be cause for concern by some and can be an annoyance for those who rely upon the Dictation Box.
Please also refer to this post: Dragon Error: “COM returned an unexpected error code: Details are HOOKERR_NONOTIFYWINDOW” for more detailed information on this connected issue.
