Hi
Does anyone have a 10-20 sec lag everytime browse folder containing expanded liveset? (Live 9 and Live 10)
It happens when I click added folder in "Place" that is currently showing a directory containing Liveset and one of them are expanded to reveal its content (by clicking the triangle icon beside the .als files.)

Step to reproduce this issue.
1. Open directory that contains your live set in browser.
2. Expand one of .als to reveal its content.
3. Click other browser category e.g. "Instruments"
4. Go back to the folder we opened in step 1.

I didn't have this issue in Live 8. I know there was lag in consulting the contents of .als file at initial access but there was no lag after that.

I checked the indexer wasn't running. And CPU was idle.
Thanks.
