I've created a new project in Sonar X3, and adjusted the song tempo to 114 bpm.  Now, all the measure markers on the timeline are off by .03 seconds...the first is at 0:02:03, the second at 0:04:06, the third at 0:06:09...how do I adjust the timeline so all my measure markers are at second boundaries (0:02, 0:04, 0:06....).
 
Thanks for any advice!

I don't see how that would be possible, there's a fixed relationship between tempo/measure length and time. For example at 120 BPM, a measure lasts exactly 2 seconds. If you slow down the tempo, it will last longer than 2 seconds. There's no way I know of to "fool" SONAR into thinking that a measure at 114 BPM correlates to a time other than about 2.03 seconds.

In my no-sleep addled brain last night, the below question seemed reasonable.  Once I realized that if I have M:B:T set as my unit of measure on the timeline, and I set the song clock to M:B:T rather than H:M:S:F, everything lines up.  Thanks, Craig, for the answer that forced my brain to start thinking again!
