I'm working on a project where I need to delete a section of the begining. I have the section marked of with 2 markers. I select all of the audio tracks between the markers. I go to edit and choose cut and delete hole. some of the tracks snap to the left but edited tracks do not. how come sonar 8.5 does this perfect and sonar platinum does not? does anyone have a work around for this?
 

Turn on ripple editing for all tracks.

This has been a known issue for a while now and that's why Ripple edit was created.
Have you tried using Ripple edit ? It works amazingly well for situations like this.
 

what version of platinum is this included. I stop updates awhile back.

Work around without ripple editing? remember 8.5 did this perfectly.

Work around without ripple editing? remember 8.5 did this perfectly.
 

Your right, 8.5 did a lot of things perfectly but that was 10 years ago. It was also lacking in the features department.
Ripple editing was added in 3 months ago. So im not sure what to tell you.
 
The work around is:
-Split tracks; using the keyboard shortcut "S".
- Delete the track sections you want removed.
- Hold down LEFT click and "Lasso" the clips (this selects) you want to move.
- Once all tracks are selected that you want to move, Grab 1 of them and slide the material over.

Another work around (for delete hole itself to function) is that all tracks must have data in them (prior to ripple editting). There must be data in the hole on both MIDI and audio tracks or else SONAR deselected them and only shifted ones with deleted data.

There was a great work around by Squirebum "Ron" in one of these threads but I couldn't find it.
Ironically I think his approach got on my nerves but It was a great, well thought out method to delete and slide.
