I finally got a chance to try to recreate the Pro Channel scrolling issue that I'd seen (or at least one variation). It turned out to be pretty simple to do with a very small project with 3 instrument tracks and 2 buses, each with enough Pro Channel Modules on it to need to be able to scroll. Here is the problem report I just submitted to Cakewalk to describe it -- I'm guessing most should be able to recreate something similar to this pretty easily, with one key being to just select and unselect an applicable track, hovering your mouse over Pro Channel and using the scroll wheel in between, and sometimes switching back and forth between buses and tracks and doing the same in between.
In my estimation, Pro Channel should always scroll (if scrolling is applicable on the track or bus) if you hover the mouse over it and use the mouse wheel. You shouldn't have to click on a module in Pro Channel to restore scrolling functionality, and it should matter whether a track's selection is toggled or not.
CWBRN-11100 Pro Channel sometimes doesn't scroll when changing track/bus selection/focus
Steps to recreate:
1) Open sample project "X2 Pro Channel Scrolling Issue.cwp".
2) Hover your mouse over Pro Channel and move the mouse wheel.
3) Click on the "1" in the Track 1 (Rapture instrument track) header in the tracks pane.
4) Hover your mouse over Pro Channel and move the mouse wheel.
5) Click on the 2 in the Track 2 (Dimension Pro instrument track) header in the tracks pane.
6) Hover your mouse over Pro Channel and move the mouse wheel.
7) Click on the 2 in the Track 2 (Dimension Pro instrument track) header in the tracks pane.
8) Hover your mouse over Pro Channel and move the mouse wheel.
9) Click on the "1" in the Track 1 (Rapture instrument track) header in the tracks pane.
10) Hover your mouse over Pro Channel and move the mouse wheel.
11) Click on the "A" in the Bus A (Master bus) header in the bus pane.
12) Hover your mouse over Pro Channel and move the mouse wheel.
13) Click on the "A" in the Bus A (Master bus) header in the bus pane.
14) Hover your mouse over Pro Channel and move the mouse wheel.
15) Click on the "1" in the Track 1 (Rapture instrument track) header in the tracks pane.
16) Hover your mouse over Pro Channel and move the mouse wheel.
Expected results:
In all even number steps above, the Pro Channel modules should scroll.
Actual results:
The Pro Channel modules scroll in steps 2, 6, and 10, but they do not scroll in steps 4, 8, 12, 14, and 16.
