Using VP 11.8.1 (and earlier) with Windows 7 (64-bit) on two machines, I can get error messages of the following type, on one of the machines, when issuing VP commands:</p><p><img src="uploads/18/VoicePower_error_message.png" height="331" width="407" border="0" /></p><div>VP usually starts out well in each new Dragon session, then after awhile VP commands start resulting in messages like the above. I've tried toggling the "11.0 Bug" configuration option, but at this point I'm not sure it makes much difference.</div><div> </div><div>Please advise, and let me know what additional information I can provide.<br></div><div>Thanks!<br>Fred</div>
