Editing MIDI Data

Don't know if this was discussed before (I don't remember if it was) but I found some very strange behavior when copying and pasting MIDI data within the same track.

After awhile, the copy function DOES NOT bring up the little window to choose what to copy (whether hitting CNTL-C or COPY in the EDIT drop down menu) does not appear.  When this happens and you try and paste it to a new position within the same MIDI track, it sometimes ADDS a NEW TRACK and put the MIDI past the project END in the timeline and other times, it appears to not paste anything...

If I quit SONAR and come back in and try the exact same action, all is well... very STRANGE..

I am using the latest SONAR X1b with the last HOTFIX (whatever number it was).

Anyone else have this odd behavior and/or was this reported to the bakers yet?

Thanks,
Jim
